Question

I have a text-field called name in my schema.xml. A query q=name:(organic) returns the following documents:

<doc>
    <str name="id">ontology.category.1483</str>
    <str name="name">Organic Products</str>
</doc>
<doc>
    <str name="id">ontology.keyword.4896</str>
    <str name="name">Organic Stores</str>
</doc> 

This is perfectly right in a normal Solr Search, however I would like to construct the query so that it doesn’t return anything because ‘organic’ only matches 1 of the 2 words available in the field.

A better way to say it could be this: Only return results if all tokens in the field are matched. So if there are two words (tokens) in a field and I only match 1 (‘organic’, ‘organics’,‘organ’ etc.) I shouldn’t get a match because only 50% of the field has been searched on.

Is this possible in Solr? How do I construct the query?

Answer 1

Due to time contraints, I had to resort to the following (hacky) solution.

I added the term count to the index via a DynamicField field called tc_i.

<dynamicField name="*_i" type="int" indexed="true" stored="true"/>

Now at query time I count the terms and append it to the query, so q=name:(organic) becomes q=name:(organic) AND tc_i:(1) and this won’t return documents for “organic stores” / “organic products” obviously because their tc_i fields are set at 2 (two words).
