Search different terms for different fields (Complex Query)

Post #1 of 4 (1814 views)

Please help

In my LuceneDocument, I have three fields (title, library, content) and I
would like to search for 'myText' in the content field AND it should also
match 'myLibrary' in Library field.

"content:myText: AND "library:myLibrary"

It should only return hit if 'myText' is in the content and 'myLibrary' is
in the library field.

I read the Lucene FAG and it mention about complex query but does NOT give
any example. Can someone please help me with some sample code.

Thanks

Here is what the FAG say:
"A more complex queries may contain nested queries with 'and', 'or', 'not'
or 'phrase' relations. Queries may also contains specification of which
document fields to match against the various parts of the query (.e.g.
'authors' and 'title') and hints that may effects the ranking of the matched
documents ('boost' factor)."

Have you tried:
content:myText AND library:myLibrary

Note no quotes and no ':' after myText

If the quote of the FAQ (not FAG, fag is a slang (derogatory?) term for
homosexuals) entry is the real version then there are some typos to fix
there...

It sounds like the "complex" query you are looking
for is a BooleanQuery which links different queries
together.

Maybe:
BooleanQuery bq = new BooleanQuery();
bq.add(new TermQuery(new Term("content", "yourText")), true, false);
bq.add(new TermQuery(new Term("library", "yourText")), true, false);
... and then pass this Query into the searcher you are using.

I believe that BooleanQuery will return all documents that match
both of the TermQuery(s) you pass in.

Hope this helps, and goodluck,
Stephen Wong

I've posted a MultiFieldQueryParser to this list previously. Search the
archives.

I think you'll find it useful.
