Xapian Benchmark results
Hi, I am currently trying to benchmark a multithreaded xapian implementation on a chameleon baremetal instance written in C++. My workload is a 3 Gig wikipedia xml dump consisting of ~286 file of different sizes. My results are showing me that indexing on xapian is an order of magnitude faster than my lucene and lucene plusplus implementations. This is a result that I did not expect. Just want to

OP_ELITE_SET and max number of terms
Hi, When we use OP_ELITE_SET we can specify the number of terms we want to use. In http://trac.xapian.org/wiki/FAQ/EliteSet there is this text: "The number of terms which OP_ELITE_SET will use defaults to 10 (or ceil(sqrt(number_of_subqueries)) if there are more than 100 subqueries), but may be set by specifying a parameter to the query constructor" is it possible to use only the

PHP / XapianQueryParser
Hi everyone, I tried sending a message as a reply a while back on my previous topic, but it didn't go through. (Tried Gmane), not even when I 'authorized' the reply. So I'll just paste it here for reference, below this message. It might help some people. But now I have one other small problem, and I'm not sure if it is actually my mistake (although I'm pretty sure it is

QueryParser: aliases and OP_AND
Hello, I'm wondering about how the QueryParser parses a query containing an "alias" when the default operator is OP_AND (by "alias", I mean a search field mapped to multiple term prefixes). With the following php code : <?php $parser=new XapianQueryParser(); $parser->set_default_op(XapianQuery::OP_AND); $parser->add_prefix('alias', 'AUT1:');

Searching using prefixes
Hi guys I'm trying to figure out how I can use probabilistic searching on a given field within a document; I've written to the list about this before, but haven't quite figured out what's required and, following a little research, I think I understand what I need to do but I'd like a clarification on this. o We have a database of a number of documents, with fields: title,

Enhance synonyms feature of the query parser (patch included)
Very few people seem to be using synonym in Xapian, I recently found some problems in the use of synonyms. Normally, I think we should not contain any prefix info in synonym table except that 'Z'. For example, I have the following synonyms and prefix info: db.add_synonym("search", "find"); db.add_synonym("Zsearch", "Zfind");

[issue] The difference between QueryParser::FLAG_AUTO_SYNONYMS and QueryParser::FLAG_AUTO_MULTIWORD_SYNONYMS
I don't know whether this is a BUG or for special purpose... According to the definition of "xapian/queryparser.h", FLAG_AUTO_MULTIWORD_SYNONYMS contains bit of FLAG_AUTO_SYNONYMS . Therefore, long as I set the parse flag with FLAG_AUTO_SYNONYMS, the query parser will automatically activate the function of FLAG_AUTO_MULTIWORD_SYNONYMS. See the below source code part from

QueryParser : some remarks
Hi to all, First, I would like to say a big thank you for the work which was done on my 'wish bug' to allow mapping one field to multiple prefixes (http://www.xapian.org/cgi-bin/bugzilla/show_bug.cgi?id=93). That's great! I have upgraded to 1.0.4 and I am revisiting my code, replacing the php query parser I wrote with Xapian's one. Everything works well, but I have some

Slow phrase performance
I've been getting excellent performance out of xapian but when searches on phrases of common terms such as [ "north america" ] or [ "art history" ] get run it will take a very long time to come up with results.
