Parentheses in http querystring help needed

Elastic Stack Elasticsearch
1

Dear list,

We are running EC on top of a Mongo DB and it works great. An iPhone client
queries EC through http calls.

I would like to be able to have the search term include parentheses and a
colon, I have tried to escape and encode the parentheses as per the Lucene
docs (see sample query string below), but it does not seem to work
properly, is there anybody out there who knows how to do this?

?q=rechtsgebied_rechtspraak:%22Belasting%22+%22%5C%28hierna%5C:%20de%20Wet%5C%29%22&default_operator=AND&sort=datum_gepubliceerd_ymd:desc&size=20&from=0

This part is what this request is
about: %22%5C%28hierna%5C:%20de%20Wet%5C%29%22

Unencoded it reads: (hierna: de Wet)

Many thanks,

Diederik

Hello Diederik,

It depends on what's the
analyzerhttp://www.elasticsearch.org/guide/reference/index-modules/analysis/you're
using for both indexing and searching. For example, if on indexing
you have not_analyzed and you have a string with parentheses, the generated
token will include everything, even the parentheses. But when you search,
the default query
stringhttp://www.elasticsearch.org/guide/reference/query-dsl/query-string-query/uses
the standard
analyzerhttp://www.elasticsearch.org/guide/reference/index-modules/analysis/standard-analyzer/.
Which will take out your parentheses as if you didn't specify them.

You can use the analyze
APIhttp://www.elasticsearch.org/guide/reference/api/admin-indices-analyze/to
check how various analyzers break down your text. For example, the
standard analyzer escapes parentheses:

curl -XGET 'localhost:9200/_analyze?analyzer=standard&pretty' -d '(test)'

{
"tokens" : [ {
"token" : "test",
"start_offset" : 1,
"end_offset" : 5,
"type" : "",
"position" : 1
} ]
}

Best regards,
Radu

Here is an example query with the query_string. Note that the parenthesis
are there, but they act as if they aren't (because they aren't needed but
are still logically correct):

{
"from" : 0,
"size" : 20,
"query" : {
"bool" : {
"must" : {
"query_string" : {
"query" : "(gn: curly)"
}
}
}
},
"version" : true,
"explain" : false,
"fields" : [ "_ttl", "_source" ]
}

And here is the JSON source from the response:

{ "telno" : "7214560001" , "cnam" : "THREE STOOGES" , "gn" : "Larry, Curly,
and Moe" , "o" : "Columbia Pictures" , "addr" : "Grover St" , "city" :
"Hollywood" , "state" : "CA" }
