Guys,
Hi, I have a document with many fields, and one of them is an array (a
topics array). Currently that array has only one entry per document but in
the future we'll have more entries. The thing is that I can't make an exact
query on the topic array field when looking for more than one term in it.
Let say the documents stored have one of the following values on that
field: _Martin_, _Martin Ariel_, _Ariel_, _Kyheo_
So a doc will look something like this:
{
'text': 'some random text',
'date': '2011-12-12T15:17:35.000Z'.
'topics': ['Martin']
}
I'm doing this query (1) and the problem is that all the docs with _Kyheo_or
_Martin_ or _Martin Ariel_ in the topic field are returned, but I only want
those having _Kyheo_ or _Martin_. I'm stuck, looked in the docs but got
confused. Any help please ?
Thanks,
Martin

Make the field as not\_analyzed, then it will be exact match. Though, in
your case, you are testing for lowercase value, so if you want to ignore
casing, you will need to create a custom analyzed with a keyword tokenized
and a lowercase filter, and then associate it with the topics field in your
mapping.
