Hi,
I use a boolean query and add individual queries to it.

Subject: Querying multiple fields of a index


Hi,

Is it possible to query multiple fields of a given index and get the result
based on this combined query.
i.e for example if i want to serach for a word "lucene" in the title field
and the word "engine" in the summary filed and want the results based on
these words .

How can i achieve this ?

TIA

Regards
Harpreet

Hi,

If you are using the queryParser and the standardAnalyzer you would use a
querystring like


title:lucene AND summary:engine


So the pattern is <field name>:<search string without spaces (unless your
searching a phrase)>

Also, you don't have to explicitly put the field name if you are searching
the default field. That is if title is the default field the search would
be

lucene AND summary:engine

Hope this helps.

ok, the discussions are about passing some field names...

how about in situation where i don't have to pass any field name but
just do a complete search in all the fields...

hope someone can clarify....

First of all lemme ask sorry to the forum (lucene-user) and you Otis (in
particular) for the previous mail.

That was supposed to be addressed to our in-house forum inorder for my
team-mates to gain some knowledge.
Actually, I know how to achieve this.

Sorry for the trouble again.
