Restrict result returned by Morelikethis
Hi,
I have made a Morelikethis query to look up documents that match a certain
document id. This results in a search of the whole index. I would like the
Morelikethis query to search only part of the index. How can I do this?
I have already tried to create a BooleanQuery, like:
BooleanQuery comboQuery = new BooleanQuery();
comboQuery.add(mltQuery, true, false);
comboQuery.add(originalQuery, true, false);
But I get the error: cannot find symbol
[javac] symbol : method add(
org.apache.lucene.search.Query,boolean,boolean)
What is the correct way to restrict the search area of a Morelikethis query?
Any help is welcome. Thanks.
Kind regards,
Nick Snels

Thanks for the reply. I was indeed using the 1.4.3 API, when I actually had
to use the 2.0 version. Thanks for pointing that out. Everything is working
now.
Kind regards,

You appear to be trying to use an old method from the java 1.4.3 API for
BooleanQuery, but i'm assuming you are acctually using Lucene 2.0 or 1.9
... take a look at the 2.0 javadocs for BooleanQuery and i think you'll
see how do what you are attempting...
