I defined
routes.kategoriler.route = ":lang/categories/:cat/:name"
routes.kategoriler.defaults.controller = "category"
routes.kategoriler.defaults.action = "index"
routes.categories.route = ":lang/:type/:cat/:name"
routes.categories.defaults.controller = "types"
routes.categories.defaults.action = "index"
type catches "categories" word. I put definitions before and after but no way. Can you offer a solution?
Use a requirement for type to do not match 'categories'. Like this:
routes.categories.reqs.type = "[^categories]"
Sadly my regex skills aren't on the top, so you might want to rewrite it (It's a little ugly, and it disapproves anything that contains 'categories', but it gives you the idea.)
using hint from
Regular expression to match a line that doesn't contain a word?
routes.categories.reqs.type_name = "^((?!categories).)*$"
Solved my case
To be able to accept anything except the exact match of "categories" use the below regexp
^((?!^categories$).)*$
this will allow you to use the type as "my-categories" or "categories-of-products" or anything else that is not an exact match of "categories"

I have a list of maps (bText) and the map of field names include (kjvtext, nasbtext, esvtext) string fields.
I have another preferences variable: String bVersion = "esvtext";
I want to access the map field bText[index].esvtext when the bVersion field contains "esvtext" and field bText[index].nasbtext when the bVersion field contains "nasbtext".
I've tried several combinations of code such as:
Text(bText[index].bVersion)
Text(bText[index].[bVersion])
Text(bText[index]."$bVersion")...
I've finally resorted to:
xText = (bVersion == "kjvtext")
? verselist[index].kjvtext
: (bVersion == "nasbtext")
? verselist[index].nasbtext
: (bVersion == "esvtext")
? verselist[index].esvtext
: "bVersion version error\n",
Seems like there would be a simpler way to code this?
Any thoughts? Thanks in advance!
I have in my index a list of object, each of them has an objectID value.
On some search, i want to filter OUT a certain number of them, using there objectID.
For the moment it works with one value as a string, i would like to know how to do for multiple value.
filters = 'NOT objectID:' + objectIDToFilter;
This work for one object, what can i do to apply this for an array of ObjectID. because :
filters = 'NOT objectID:' + arrayObjectID;
does not work.
I was thinking of generating a huge string with an arrayId.map with all my 'NOT objectID:1 AND NOT objectID: 2 ...' but i wanted to know if there is a cleaner way to do it.
I unfortunately misunderstood the line in algolia doc :
Array Attributes: Any attribute set up as an array will match the filter as soon as one of the values in the array match.
This apparently refers to the value itself in Algolia and not the filter
So i did not found a solution on algolia doc, i went for the long string, hope there is no limits on how much filter we can add on a query (found nothing about that).
Here is what i did if someone need it :
let filters = `NOT objectID:${userID}`;
blockedByUsers.map((blockedByUser) => {
filters = filters + ` AND NOT objectID:${blockedByUser}`;
});
If you need to add multiple but don't have a starting point like i do, you can't start the query with an AND , a solution i found to bypass that:
let filters = `NOT objectID:${blockedByUsers[0]}`;
blockedByUsers.map((blockedByUser, i) => {
if (i > 0) filters = filters + ` AND NOT objectID:${blockedByUser}`;
});
There is probably a cleaner solution, but this work. If you have found other solution for that problems i'll be happy to see :)
I can't perform a wildcard-query on an embedded-list property of vertex (or edge).
For example:
Assume we have a Person class with a multi-value property named Nicknames and one instance of it:
{
"#type": "d",
"#rid": "#317:0",
"#version": 1,
"#class": "Person",
"Nicknames": [
"zito",
"ziton",
"zitoni"
]
}
then,
Select FROM Person WHERE Nicknames like "zit%"
returns empty result-set, while:
Select FROM Person WHERE Nicknames ="zito" returns 1 item correctly.
There's a NOTUNIQUE_HASH_INDEX index on the field Nicknames.
I've tried many ways (contains, index-query...) with no luck :(
I'm probably missing something basic.
I know is not an ideal solution what i'm going to write but, to stay stuck with your requirement of "query by wildcard" this is the only way that worked for me, as AVK stated is a better idea work with a Lucene index, but with the standard implementation i was unable to let it work, now here what i've done:
Use studio to create a javascript function with 2 parameter with name "array" and "rule", lets name the function "wildcardSearch"
past this code in the body of the function (is just simple javascript change it if it dosent do the job) :
for(i=0; i<array.length ; i++){
rule= rule.split("*").join(".*");
rule= rule.split("*").join(".*");
rule= "^" + ruleValue + "$";
var regex = new RegExp(rule);
if (regex.test(array[i]))
return true;
}
return false;
Remember to save the fucntion
now you can query:
Select from Person where wildcardSearch(nicknames,'zit*')=true
CONSIDERATIONS: is a brute force method, but show how "funny" can be play around with the "stored procedure" in OrientDb so i've decided to share it anyway, if performance are your main goal this things is not for you, it scan all the class and do the loop on the array to apply the regex. An Index is a way better solution, or change your db with a different data structure.
You can try this:
select from Person where Nicknames containstext 'zit'
Hope that helps
I have a requirement to fetch search results based on partial text match. For example, if there is a node under products say "apple-iphone-6" and the user enters "iphone" text in the searchbox, I should still be able to fetch the result.
I tried the below query on querybuilder and it worked:
http://localhost:4502/bin/querybuilder.json?path=/etc/commerce/products&type=nt:unstructured&nodename=*iphone*
But, how to implement this programatically for the *iphone* part? I am creating a query using the predicates as follows
String searchTerm = "iphone";
map.put("path", "/etc/commerce/products");
map.put("type", "nt:unstructured");
map.put("nodename", searchTerm);
Query query = queryBuilder.createQuery(PredicateGroup.create(map), session);
SearchResult result = query.getResult();
But I do not get any results, reason being, the node name(apple-iphone-6) does not exactly match the search term (iphone).
But the same thing works fine in case I append * to the nodename value which then implements partial text based search in the querybuilder example. What change should I do in the code to get results based on partial node name matches?
You already have found the solution on your own, the NodenamePredicateEvaluator accepts wildcard arguments, so you would need to surround the search term with wildcards, for example like this:
String searchTerm = "iphone";
...
map.put("nodename", "*" + searchTerm + "*");
in this case "like" opration can be used:
EX-> patial text serach for jcr:title
map.put("group.1_property", "fn:lower-case(#jcr:content/jcr:title)");
map.put("group.1_property.value", "%"+fulltextSearchTerm + "%");
map.put("group.1_property.operation", "like");
For just the nodename the answer posted is correct, but if you want to search inside properties as well then :
map.put("fulltext","*"+searchTetm +"*");
map.put("fulltext.relPath","jcr:content");
I've got an array like that
Word array (
{
translation = (
{
name = Roma;
lang = it;
},
{
name = Rome;
lang = en;
}
);
type = provenance;
value = RMU;
},
{
translation = (
{
name = "Milano";
lang = it;
},
{
name = "Milan";
lang = en;
}
);
type = destination;
value = MIL;
},)
The idea is to filter it using an NSPredicate and receive and an array of dictionaries based on the lang key, I'd like to get something like this made by filtering for lang == it,
Word array (
{
name = Roma;
lang = it;
type = provenance;
value = RMU;
},
{
name = "Milano";
lang = it;
type = destination;
value = MIL;
})
I can't simplify the data because it comes from a "JSON" service.
I've tried different predicates using SUBQUERY but none of them works, documentation about SUBQUERY is pretty poor, I'm missing something, probably the problem is that I'd like to receive an object that is really different from the source.
Of course I'm able to obtain that structure enumerating, I'm wondering if there is a shorter solution
This answer from Dave DeLong link to SUBQUERY explanation gave a me a lot of hints about SUBQUERY, but I'm not able to find a solution to my problem.
Can someone give me a hints about?
You can't do this with a predicate. (Well, you could, but it would be stupidly complex, difficult to understand and maintain, and in the end it would be easier to write the code yourself)
NSPredicate is for extracting a subset of data from an existing set. It only* does filtering, because a predicate is simply a statement that evaluates to true or false. If you have a collection and filter it with a predicate, then what happens is the collection starts iterating over its elements and asks the predicate: "does this pass your test?" "does this pass your test?" "does this pass your test?"... Every time that the predicate answers "yes this passes my test", the collection adds that object to a new collection. It is that new collection that is returned from the filter method.
THUS:
NSPredicate does not (easily) allow for merging two sets of data (which is what you're asking for). It is possible (because you can do pretty much anything with a FUNCTION() expression), but it makes for inherently unreadable predicates.
SO:
Don't use NSPredicate to merge your dataset. Do it yourself.
