More like this on numbers


(Valentin Pletzer) #1

Hi,

as far as I understand it the more like this query allows to find documents
where the same tokens are used. I wonder if there is a possibility to find
documents where a particular field is compared based on its value (number).

Regards
Valentin

Hi Valentin,

As you know, you can only perform mlt on fields which are analyzed.
However, you can convert your other fields (number, ..) to text using a
multi field with type string at indexing time.

Cheers,

Alex

Hi Alex,

thanks. Good idea to convert the numbers into strings. But converting the
number fields to string won't exactly solve my problem. Only if there would
be an analyzer which breaks down numbers into multiple tokens. Eg 300 into
"100", "200", "300"

Cheers,
Valentin

Hi Valentin,

For these types of searches, have you looked into range queries, perhaps
combined in a boolean query?
