We use Sphinx Search at work but and I am having an issue with a new index I'm setting up. Does anyone know of a tool or technique that so I can look at the data stored in Sphinx?
Basically I want to do something like - "show me the first 5 records in index 'X'", just to be sure that it is actually storing data. At the moment I'm about 90% sure that my query code is correct but have no way of knowing that my index is correct.
Cheers
*SELECT * FROM index_name* on Sphinx side should give you a list of IDs. This required MySQL protocol support to be enabled in Sphinx conf file:
listen = 9306:mysql41
To Find Ids in index, you can do this:
/usr/local/sphinx/bin/indextool -c /usr/local/sphinx/etc/sphinx.conf --dumpdocids indexname

I am new to cassandra (started learning on my own interest few days back) and looking for help for the below problem.
I have a Cassandra table "User" and a ListColumn "interests extends ListColumn[String]".
Now, I want to fetch all users with an interest, say "playing".
like: select from user where interests.contains("playing")!
I scanned through the ListColumn api but not able to find any. Also, searched in google but no such helpful posts.
Any help guys please... Thanks in Advance :)
So there is contains among operators and here is an example how to use it. It looks like that it should work as any other operator, so just go for database.userTable.select.where(_.interests contains "playing").fetch() - of course, depending on your conventions.
This is possible with a secondary index on a collection column, which only works with a Set column, and not with a List.
Bottom line:
object interests extends SetColumn[String](this) with Index[Set[String]]
And then you can execute the following:
select.where(_.interests contains "test").fetch()
You can also use multiple restrictions if you allow filtering.
select.where(_.interests contains "test")
.and(_.interests contains "test2")
.allowFiltering()
.fetch()
The above will only match if both interests are found in a record.
how can i write this query on sphinx select * from vehicle_details where make LIKE "%john%" OR id IN (1,2,3,4), can anyone help me? I've search a lot and i can't find the answer. please help
Well if you really want to use sphinx, could perhaps make id into a fake keyword, so can use it in the MATCH, eg
sql_query = SELECT id, CONCAT('id',id) as _id, make, description FROM ...
Now you have a id based keyword you can match on.
SELECT * FROM index WHERE MATCH('(#make *john*) | (#_id id1|id2|id3|id4)')
But do read up on sphinx keyword matching, as sphinx by default only matches whole words, you need to enable part word matching with wildcards, (eg with min_infix_len) so you can get close to a simple LIKE %..% match (which doesnt take into account words)
Actually pretty hard to do, becuase you mixing a string search (the LIKE which will be a MATCH) - with an attribute filter.
Would suggest two seperate queries, one to sphinx for the text filter. And the IN filter just do directly in database (mysql?). Merge the results in the application.
is it possible to temporarily disable & again enable of an index on a table in db2luw.
If so can some one tell me the syntax or process, to achieve this.
I am updating tons of records . Before that I have to disable all the indexes on all the tables & after that have to create only one user created index (I9) on all the tables. My update query has to be run only with one index(I9).
When once my update query got completed. again I have to reset all the tables to their original position(previous indexes).
I am very new to db2. kindly excuse me if I am wrong at any stage in my question.
That is what I am trying to find.
If you have a better solution for this, can you please let me know.It l be a very good favour.
Thanks
You can't "disable" an index. Please see DROP INDEX <name> and CREATE INDEX <name>.
I'm currently experimenting with sphinx realtime index. I inserted 4,5 millions documents.
Everything was working OK while my json meta attributes were like this:
{"result_type":"publications","publication_type":"essay"}
But yesterday, I wanted to add another value in 'publication_type' key and the json
resulted to:
{"result_type":"publications","publication_type":["essay","big_text"]}
Now I can't find document neither for 'essay', neither for 'big_text'.
The sphinxql query I'm using is like this:
select * from url where meta.publication_type='essay';
Sphinx version is Server version: 2.1.1-beta (rel21-r3701) running on Debian.
Hope you can help me. Is my json string wrong? Where is my mistake?
Thanks in advance.
SELECT *, ANY(x='essay' FOR x IN meta.publication_type) as p FROM url WHERE p=1;
Supported in 2.2.1-dev since r4217.
This was answered on the sphinx forum:
http://sphinxsearch.com/forum/view.html?id=11486
When store arrays, you access the values by index.
So could do
select * from url where meta.publication_type[0]='essay';
It doesnt appear to easy to search 'in any position'. So if essay was ever not the first index, it wouldnt work.
Note, I can't claim credit for figuring this out, just passing this information on.
HI
I have used "setResultSetLimit(1000)" method to limit results to 1000 records. The good thing is It helps to save server resources, but there is noway to get full record count for a query. Is any one know how to get full hit count?
TX
Its not possiblie within my tries...
I suggest u to make a full search store results making a cache file maybe or session and use zend_paginator array adapter
The answer is so easy or I didn't understand the question ?
$results = $index->find("saerch term");
echo count($results); // you will get count
