Your query is a tree, with BooleanQuery as branch and other query as
leaf. If you wont to transforma query

Objet : Error tolerant text search with Lucene?
Hi everyon
Hi everyone,
I know that there are packages that support the "Did you mean ... ?"
search features with lucene which tries to find the most suited
correct-word query.. however, so far I haven't encountered the opposite
search feature: given a correct query, find all documents which contain

That is why the original contrib does not work with PhraseQuery's. It
simply matches Tokens from the query with those in the TokenStream.
LUCENE-794 takes the TokenStream and shoves it into a MemoryIndex.
Then, after converting the query to a SpanQuery approximation,

Oh yeah...something that you may not have seen is that this has a
dependency on MemoryIndex from contrib. You need that jar as well.

It seems that the patch does not work with Lucene 2.2 as I get some

OK, before trying it out, I would like to know does the patch work for
mixed queries, e.g. "a b" +c -d "
Dear all,
Let's assume I have a phrase query and a document which contain the
phrase but also it contains separate
occurrences of each query term. How does the highlighter know that

Hi Marjan,
Lucene process the query in what can be called

For the example query - x y - (not the phrase query "x y") - all

When processing the query - x y - the posting lists of these two

Dear all,
Maybe this topic is already discussed (then can I get a reference
please?)... I would like to know how does Lucene actually process the
query. For example, take a 2-word query "x y". Does Lucene fetch the
lists of "x" and "y" and intersect them, or do they do something more
fancy, f
Dear all,
I am a new Lucene user and I would like to know the following. How does
Lucene bring together fuzzy queries and highlighting?
Let's say for the query algorithm, the word algorith is also a match,
how do the highlighter know that it should also highlight
occurrences of the word algo
