I'm having a post, each post has tags (varchar[]), and I'm trying to find related ones according to tags. This is why I want to check if all tags of the target post or any of its subsets are contained in the 'tags' arrays of other posts.
I've checked several sources:
Postgres: check if array field contains value?
https://www.postgresql.org/docs/9.1/functions-array.html
According to them, #> should be suitable for this case, however neither
select * from posts where tags #> '{"California", "K-8"}';
nor
select * from posts where tags #> array['California', 'K-8']::varchar[];
work properly: I got an empty result while I have two posts with tags:
{'California','K-8','Legislation','AB77'}, {'California','K-8','Tips & Tricks'}
I would greatly appreciate it if someone could advise a solution to this issue :-)
EDIT: I've figured out what was wrong - the issue was in the format of stored data: after I had changed
{'California','K-8','Tips & Tricks'}
to
{California,K-8,"Tips & Tricks"}
in pgAdmin everything started to work properly.

I am setting a Variable in Grafana.
I want to create a Query, that only returns a subset of the labels with value app the ones I want to return are those ending in dev
My Query so far, returns all of the labels with value app successfully. However, I have been unable to successfully filter the values so that only a-dev b-dev and c-dev are returned.
How do I successfully apply regex (or alternative) to this query so that I can see the desired values?
Any help on this would be greatly appreciated!
I eventually figured out what I needed to do. Originally I was trying to use | to run regex on the results from label_values.
However, this format worked:
label_values({app=~".*-dev$"}, app)
and returned only a-dev b-dev c-dev as expected.
I'm trying to produce a query that will return all pages under a path where a property is NOT present.
Effectively I want the query builder query that will produce the following xpath: /jcr:root/content/site/my/path//element(*, cq:Page)[not(jcr:content/task/#finished)]
For CQ 5.3 the 'exists' property doesn't seem to be present (according to the docs: http://docs.adobe.com/docs/en/cq/5-3/javadoc/com/day/cq/search/eval/JcrPropertyPredicateEvaluator.html), however it looks like I can use 'not', so I've tried the following two examples but neither work as I expect in query debugger:
1
path=/content/site/my/path
type=cq:Page
property=jcr:content/task/finished
property.operation=not
2
path=/content/site/my/path
type=cq:Page
property=jcr:content/task/finished
property.operation=not
property.value=true
I've also seen pages that suggest these should work, and I can't seem to see any hotfixes that would cover fixing this (assuming it isn't actually working correctly).
Can anyone offer a solution or point out where I'm going wrong?
Using CQ 5.3, upgraded to crx 2.2.

I have a few resource that I hope help you:
My blog post about query API options: http://itgumby.github.io/blog/2014/10/cq-queries-demystified/
6 Dimension's post about specific query examples: http://labs.sixdimensions.com/blog/2014-10-07/9-jcr-sql-2-queries-every-aem-dev-should-know/
Adobe QueryBuilder documentation: http://docs.adobe.com/docs/en/aem/6-0/develop/search/querybuilder-api.html
Non-empty SQL2 (From the 6D post):
SELECT * FROM [cq:PageContent] WHERE [jcr:title] IS NOT NULL
Which means you could convert that to WHERE [jcr:title] IS NULL
If using QueryBuilder predicates, the property generally won't exist (deleted from node) if it is false. Please manually verify in your case using CRX-DE lite and examining the node & its properties. If the property does exist, but its value is false, then:
path=/content/site/my/path
type=cq:Page
property=#jcr:content/task/finished
property.value=false
For any still struggling, this is how you do it
path=/content/site/my/path
type=cq:Page
property=jcr:content/task/finished
property.operation=exists
property.value=false
Right now the Facebook API is returning a URL like this with all post/album images 130x130 pixels in size:
https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-xfp1/v/t1.0-9/s130x130/10801504_570625556403546_6496651209845129904_n.jpg?oh=dcf8ab3752522532871d2aaab09b6e7e&oe=54E4402F&gda=1424027679_76464aeeaa5d232b8100d01476af4ec7
How do I retrieve a full (or any bigger size) image based on that URL?
For example this one:
https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-xfp1/v/t1.0-9/p417x417/10801504_570625556403546_6496651209845129904_n.jpg?oh=cd2b5cb0d74f7306c098de9f56dc6e27&oe=54E1F4C1&gda=1423830001_e700bfac39039952bfee55b200c158bf
or anything like that?
All the other suggestions of removing s130x130 from the URL, or /v/t1.0-9/, or replacing _s with _n or anything like that aren't valid any more - I've tried them all (try them yourself if you don't believe me). Is there a way to make this happen? Not sure what Facebook guys have changed to disable that...
After a couple of hours searching and pulling my hair out, I found a solution that works for me. In my case I'm pulling posts from {page-id}/posts, but I'm pretty sure this will work for you too, seeing that I used to get larger images using the same approach as you mention.
This is works for me:
bigger_image="https://graph.facebook.com/" + picture_url_from_facebook.match(/_\d+/)[0].slice(1) + "/picture?type=normal";
/_\d+/ matches any substring starting with an underscore (_) followed by any digits (\d matches one digit, \d+ does the digit match over and over until it fails)
match(regex) returns an array with all strings it could find matching the specified regex
we grab the first ([0]) element, as this will be an underscore followed by the ID of the picture in Facebook's database
we slice the string from index 1 to the end, as the underscore is not a part of the ID
we then get a working link from facebook using the graph api without the need for any extra calls (you can use this in for example an img tag directly)
You can see this working in action # this fiddle or this page we did for a client
Thanks to Er Adhish for leading the way to the solution # https://stackoverflow.com/a/27075503/2908761
https://graph.facebook.com/{object_id}/picture?type={thumbnail|album|normal}
Example (using a bogus object_id of 122233334444555):
https://graph.facebook.com/122233334444555/picture?picture?type=large
Make sure object_id is not just the id of an item but it's object_id (which is typically the number following the underscore in the full id).
I got those type values from a helpful facebook response message that said:
"message": "(#100) type must be one of the following values: thumbnail, album, normal"
In place of ?type=... you could do height/width as well:
?width=543&height=543
I want to use some keywords that include special characters like & in Facebook search api. I tried the query below but I cannot get useful results. Is there any chance for this usage in search api? How should I build my search query?
My example queries and keywords are "H&M", "marks & spencer",
http://graph.facebook.com/search?type=post&limit=25&q="H&M"
http://graph.facebook.com/search?type=post&limit=25&q="marks & spencer"
My team worked on this forever, ended up finding this as a solution that provides relevant results for a query with an ampersand, such as 'H&M'.
%26amp%3b
This is the hex equivilent to &
So your example link would be
http://graph.facebook.com/search?type=post&limit=25&q="H%26amp%3bM"
We found the solution thanks to Creative Jar
You want %26 which is the URL encode for ampersand so
http://graph.facebook.com/search?type=post&limit=25&q="H%26M" http://graph.facebook.com/search?type=post&limit=25&q="marks %26 spencer"
Depending on your language, it may have a URL encoding function or you can just use string replacement.
It seems, that all of solutions suggested here are not working any more.
Searching for q=H%26%bM returns empty data set. The same for q=H%26M.
It must have changed recently, in last 2 months.
If you try to search for postings about H&M on Facebook site (type H&M in search, then "Show me more results" on the bottom of list and then public posts on menu on the left side) the list is empty.
The only query that returns any results is q=H&M but it is not helpful, as the results are irrelevant for that query.
This query gives visits by traffic source;
https: //www.google.com/analytics/feeds/data?ids=ga%3A123456&dimensions=ga%3Asource%2Cga%3Amedium&metrics=ga%3Avisits&sort=-ga%3Avisits&start-date=2009-08-12&end-date=2009-08-26&max-results=50
But, when specifying a filter: ga:pagePath==/Default.aspx - I get zero results
https: //www.google.com/analytics/feeds/data?ids=ga%3A123456&dimensions=ga%3Asource%2Cga%3Amedium&metrics=ga%3Avisits&filters=ga%3ApagePath%3D%3D%2FDefault.aspx&sort=-ga%3Avisits&start-date=2009-08-12&end-date=2009-08-26&max-results=50
How can i filter on ga:pagePath?
query1.Dimensions = "ga:date,ga:pagepath"
query1.Metrics = "ga:pageviews"
query1.Sort = "ga:date,ga:pagepath"
query1.GAStartDate = "2010-09-01"
query1.GAEndDate = "2010-09-10"
query1.Filters = "ga:pagePath=~/abc*"
hope this works for you.
Here's a very late theory to your question...
Your data query looks valid assuming you have content indexed as /Default.aspx. I've reproduced the query on my asp.net site and get back results. I can see two potential scenarios where your query may produce empty results.
The filter mechanism in Analytics is case sensitive so if by chance links come into the page as default.aspx your filter for 'Default.aspx' won't hit. I wouldn't have guessed it works this way but lately I've had to go back and fix some of our queries as they produced empty results when case mismatches occurred.
The second possible issue relates to the use of 'Default Documents'. If links are coming into your site without a file name ('/' or '/somepath/') and 'default.aspx' is setup as a 'Default Document' in IIS, then you really want the filter to be ga:pagePath==/.
