I just noticed MultiPhraseQuery has a setSlop method, so I think this Query
is what you're looking for.

You can also look up Apache Derby which is an open source DB which can be
integrated into your app (not needing an install, like MySQL which is also
free).

You can look at org.apache.lucene.search.MultiPhraseQuery which does
something similar to what you ask. From its javadoc:
* To use this class, to search for the phrase "Microsoft app*" first use
* add(Term) on the term "Microsoft", then find all terms that have "app" as
* prefix using IndexRead
Hello Mike,
thank you for the answer. Currently I hold this datastructure in a
HashTable in Memory but the ressource consumtion is very high.

perfomant. I though also to use later the abilities to lucene to attach

It seems that documents having less fields satisfying
the query worth more than those satisfying more fields
of the query, because the first ones are more "to
the point".
At least it seems like it in the example.
If this makes sense I would try to compose a top level
boolean query out of the one-
This is great stuff, thanks for posting it.

I think the results will be more interesting for indexing, which has a
lot of file merges.

Hi,
how can one search for a key containing a colon when
using QueryParser (with WhitespaceAnalyzer)
E.g.
searching for 'abc:def'
Giving this string to QueryParser's parse
method, abc: will be misinterpreted as the name
of a field. How can this be avoided?
Is there something like an escape tec

Hi,
When highlighting a phrase query like
"Erik Hatcher"
all instances of "Eric" as well as all instances
of "Hatcher" are highlighted even if they are
not next to each other.
Is this a limitation of highlighting with Lucene?
Many thanks for an explanation,
Helmut.

QueryParser ingnores tokenizing when query includes wildcard.
Here is an example using BigramAnalyzer.
Normally.
query is : abcde
parsed to : ab bc cd de
When query includes wildcard.
query is : abcde*
parsed to : abcde*
But I want below parsed result.
query is : abcde*

Good pointers, thanks. I asked because I did have a problem like this a few
months ago -- none of the existing parsers solved it for me (back then).
