Solr query to get results based on the word length (letter count)

[Giri <gi...@gmail.com>]

Hi,

I have a solar index that has thousands of records, the title is one of the
solar fields, and I would like to query for title values that are less than
50 characters long. Is there a way to construct the Solr query to provide
results based on the character length?


thank you very much!

No good way. At indexing time, I'd just store the number of chars in the 
title in a field of it's own.  You can possibly do that solely in 
schema.xml with clever use of analyzers and copyField.

Solr isn't an rdbms.  Best to de-normalize at index time so what you're 
going to want to query is in the index.

[...]

One could write a custom query parser, but if one needed that, would it
not be easier to simply index the length of the title value as a separate
field?
