Hi,
I am using StandardAnalyzer when creating the Lucene index. It indexes the
word work as it is but does not index the word wo*rk in that manner.
Can I index such words (including * and ?) as it is? Otherwise I have no way
to index and search for words like wo*rk, you?, etc.
Thanks

Hi,
Thanks, I tried WhitespaceAnalyzer too, but it seems case sensitive.
If I need to search for words like correct?, html (it escapes , and
another few characters too) I need to index those kind of words.

I think you meant Field.Index.NO and Field.Index.TOKENIZED, for those
two docs.
The answer is yes -- Lucene considers the field indexed if ever any
doc, even a single doc, had set Index.TOKENIZED or Index.UN_TOKENIZED
for that field.
However, your document A still will not have been

Then you simply add a LowercaseFilter to the chain in the Analyzer:

Hi All,
I am new to this Lucene, and I am using this for indexing and
searching. Is it possible to search substrings using this, for example if a
field holds the value LuceneIndex and if a give the query as Index, I want
to get this field also.. is there anyway for this.
Thanks in Advance,
Hi ,
You could use wildcard queries in that case (In case I got you right).
Though because of the way the indexed terms are stored, it would not be
advisable to have a *word like query but a word* like would be doable in
real world environment.
Hope this answers your question.

Hi Anshum Gupta,
Thanks for your replay, but when I gone through querySyntax-Document for
Lucene, I read that Lucene does not allow queries like *findthis i.e. I
think it doesnot allow wildcards in the beginning of the query.
is it?
Thanks,

Yes, and that is the reason why I said,

*word : is a prefix wildcard, which can be done, but its not all that
straight, and still would be highly against what I would advise

Can anyone tell me if it's possible to apply a filter to a SpanQuery and

Heiko,
It's most likely because that B case has a purely negative query. Perhaps you
can combine it with MatchAllDocs query?

ok, thanks. I knew that the documents were buffered in memory until they
were flushed, but I thought that in memory, they were still separate
documents/segments until they were merged together at the appropriate time
(dependent on the mergeFactor).
Do you mean that when the IndexWriter flushes

No, you won't need it. If you know that the field is not really tokenized

Exactly as Otis sais, you should use MatchAllDocs as query, but it has a
drawback in performance, it checks every single document deletion state,
I've solved the issue by making my own EnhancedMatchAllDocs query that is
optimized to do not check this document state.
Perhaps the SegmentReader
Mike just committed a read-only IndexReader recently. If you pull Lucene out
of the svn trunk, you'll be able to make use of that. The r-o IR doesn't have
a synchronized isDeleted, I believe.

understand how the input from reader1 and reader2 are mixed
together.
Will sink1 first reaturn the reader1 text, and reader2?
It depends on the order the fields are added. If source1 is
used first, then reader1 will be first.
For some reason, the TermQuery is not returning any results, even when
querying for a single word (like on*).
query = new TermQuery(new Term(LABEL_FIELD, searchString));

For the question, I think you must iterate all the terms in index with
TermEnum and see if term will satisfy any of your concerns.

Very Thanks. But I'm sorry I can not catch what's your meaning.
A sentence through Analyzer.TokenStream method and will get a TokenStream
result. this TokenStream will save into index with someway, now I'm just to
get all token for this input sentence from index.
