Solr过滤器查询字符串

Question

I have been working with Solr recently to filter data using set_filter_query. I was able to work with Integer values.

$solr_dao->set_filter_query('ID:[3+TO+*]');

This query filters data having values 3 or more. I am also trying to include a word search on a field using

$solr_dao->set_filter_query('Comments:[*'.$search_term.'*]');

which doesn't seem to be working. This query should filter data with comments field having the search term. Any ideas what might cause this?

Answer 1

use this instead :

$solr_dao->set_filter_query('Comments:*'.$search_term.'*');

Note that in Solr, it indexes every words. So if a row contains "Hello honey my name is John" in the column "foo", if your query is foo:Hello World, this row will satisfy the query, since Solr looks for words, and read spaces as "OR"...
