Hello everyone, I'm using Xapian at work (PHP bindings) and I have to make it accept '##' as a term to index. We have a layer on top of xapian, but as far as I can tell, Xapian's QueryParser is removing them from the query. So, if I search for just '##' I get an empty query, after Xapian parsed it. I've seen the flags this class accepts, but I can't do what I want

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

Hi, I've been using Xapian for a while. But there is a scene I don't know whether supported already. Suppose: 1. Raw query: how to make pizza 2. Parsed query: how AND to AND make AND pizza 3. Documents: d1: how to make pizza at home d2: 3 ways to make pizza d3: make pizza in 4 easy steps Question: 1. During searching process, how to retrieve d2, d3 (although they don't

Hi, Trying to learn Search::Xapian and be better at perl at the same time, I'm stuck, at the DB_CREATE_OR_OPEN error. Perl says this: ~/dev/sandbox/Xapian-perl$ ./Index1-Xap.pl 100-objects-v1.csv db "db" is not exported by the Search::Xapian module Can't continue after import errors at ./Index1-Xap.pl line 7. BEGIN failed--compilation aborted at ./Index1-Xap.pl line 7. What I

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

Ok, but suppose I have a complex query, something like "(a OR b) AND NOT c OR ##". Do I have to parse the query by myself? > Date: Mon, 4 May 2015 03:03:24 +0100 > From: olly at survex.com > To: lautaromedrano at hotmail.com > CC: xapian-discuss at lists.xapian.org > Subject: Re: [Xapian-discuss] Make Xapian accept all characters > > On Sun, May 03, 2015 at

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

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

Hello, First I wanted to say thanks for a great piece of software, thanks Olly and others who've contributed! I know that Xapian supports right-truncating, if that's the proper name for wildcard support, as in a search for "xapia*". I don't believe Xapian supports wildcards on both sides of a term, correct? Is this something that is technically unfeasable, unpalatable

Thanks for your reply. I had run vcvars64.bat,but still cann't find 'cl'. Finally I fix it, change msys2_shell.cmd: "if it is present: replace rem set MSYS2_PATH_TYPE=inherit with set MSYS2_PATH_TYPE=inherit". And other errors : # ./configure CC="cl -nologo" CXX="$PWD/compile cl -nologo" CXXFLAGS="-EHsc AR=lib -IC:\zlib-1.2.3-lib\include

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)))' 0 results

I am working with version 1.2.7 and want to use stemming and synonyms. I use the perl-bindings and get some problems. First of all: the perl-bindings dont allow the QueryParser a third argument when calling parse_query! So i cannot set a default prefix (which perhaps is the solution to my problem, but later more) i have a simple testcase: 3 documents, every document only has one word:

Hull's website) and xapian-core-1.2.8 are mentioned together on this webpage https://lists.xapian.org/pipermail/xapian-devel/2012-October/001883.html

If the subject of xapian-core apitests on MSYS/MINGW and MSYS2/MINGW is taken up it might be noted that the compiler version could be recorded, probably gcc 5.3.0 or newer, that closed pipes might be an issue, and also allocating for the location of xapian-tcpsrv. Not from my own tests but another man informed there was some problems with [MSYS2] python bindings. I am not knowledgeable of the

This is a list with some libraries that I have been looking at. The idea is to discuss the advantages and disadvantages of adding some of these libraries to Xapian. If anyone knows another library that could be add to the list it would be great!

Hello, We have Xapian-Omega installed (Linux) and working in default mode and have browsed several interesting pages on the main site, at trac.xapian.org (the wiki) and in the mailing list. Having tested various search options (up to now only for Omega) we would like to ask a couple of questions. 1. Is it possible to search for Patterns of Text with Omega and/or Xapian Queries ?

All, I've run into a couple of things using omega/omindex under cygwin. I don't think I'd attribute them to xapian, omega or omindex, but wanted to get them out to the list so that if anyone else should run into these things down the road, hopefully someone will remember and be able to help. 1) after compiling and building omega, and doing make install, I get a set violation when
