Search docs with terms that match a pattern
Hello,
I have once again a small question: Is it possible to search a pattern
like "*foo*" ? I saw that we can use QueryParser::FLAG_WILDCARD but
only with "foo*" patterns. Have you got a trick to do that ?
And an other question with wildcards: i tested FLAG_WILDCARD and the
QueryParser, but i have some problems with special characters (by
example "/"). Is it possible to use escape characters to do that? I
tried &quo...

"and" without boolean operators
Salve,
Thank you very much for your kind answer. Spelling correction works very
well now. I have just one more question.
I am using Xapian::QueryParser() to create the Query. The flags are:
FLAG_PHRASE | FLAG_LOVEHATE | FLAG_WILDCARD
If I search, lets say for "king queen" (without quotes), I get all documents
with either "king" or "queen". Is there a chance to find only documents with
"king" and "queen" without boolean operators (like Google)?
Thank you very much

Wildcards
Hello,
Thanks Olly , by following to your suggestion I could do the indexing in
the CSV file while the
search results retrieved from the Postgres and it's working fine.
[ I am using the Xapian PHP-binding to index and search.]
How could I enable the WILDCARDS in it ?
I followed with the online manual which says it is disabled by default
there given some method to enable
but I am not

set_max_expansion in perl-bindings?
Hi,
I've just noticed that set_max_wildcard_expansion() has been removed in
favour of set_max_expansion() in Xapian.
Has the new method been added to the Perl-bindings?
We have some old Perl code that uses set_max_wildcard_expansion(), and I
have a test of too large expansion that now returns "something terrible
happened" instead of"Exception: Wildcard ... expands too much

xapian bug tracker registration email is not working
I tried to register yesterday, twice with 2 email addresses. The website
said it sent me mail, I never got a mail. Someone else, please confirm
this is broken.
A bug I'd like to file is that I'd like an option to search
*word. Currently you can only search word*. The example where I would
find this useful is searching for urls and email addresses. For example,

FLAG_BOOLEAN_ANY_CASE does not work
I have found that lower cased boolean operators such as "and" or "or"
does not work. Of course I never forget setting FLAG_BOOLEAN_ANY_CASE flag.
QP seems to treat them as terms.
Just look at the following tests regardless of search results!
$ python search.py -v woman AND man
Performing query 'Xapian::Query((woman:(pos=1) AND man:(pos=2)))'

QueryParser lowercase / uppercase and stemming
...myQueryParser->setStemmer($stemmer);
$myQueryParser->setStemmingStrategy(STEM_ALL);
#$querystring = removeUmlaute($querystring);
#wildcard search
$myQuery = $myQueryParser->parseQuery($querystring,
Xapian::FLAG_PHRASE|Xapian::FLAG_BOOLEAN|Xapian::FLAG_LOVEHATE|Xapian::FLAG_WILDCARD);
...
So what am I doing wrong?
The second thing I wondered about, is there any possibility to forbid
queryparser lowercasing of the query string. At least for exact phrase
matching I found this quite meaningful. (Data is indexed both, upper-
and lowercase)
Another thing is the encoding of...

Chinese, Japanese, Korean Tokenizer.
Hi,
I am looking for Chinese Japanese and Korean tokenizer that could can
be use to tokenize terms for CJK languages. I am not very familiar
with these languages however I think that these languages contains one
or more words in one symbol which it make more difficult to tokenize
into searchable terms.
Lucene has CJK Tokenizer ... and I am looking around if there is some
open source that we
