Multivalued Boolean Search

Hi

I have a multivalued field say "MulField" in my index that have values in a document like 

<str name="DocID">1</str>
<arr name="MulField">
    <str>Auto Mobiles</str>
    <str>Toyota Corolla</str>
</arr>

No let say I specified a search criteria as 

+MulField:Mobiles +MulField:Toyota 

now my question is it is possible that this document should not appear in the search results.

Regards
Ahsan

No. You should index separate two documents in your example. e.g. Normalize your data.

However there is one trick that you can use. Issuing a phrase query may satisfy your needs. e.g. q=MulField:"Mobiles Toyota"~99

Use a big positionIncrementGap value in your field definition.
