Hi all, I've come across an issue caused when I try to set the query parser's default op to OP_PHRASE: Xapian raises an Unimplemented Error if the query contains hyphenated words or other terms that implicitly generate a phrase. This can be shown with the following Python extract: >>> from xapian import * >>> qp = QueryParser() >>>

Hi All, I used the OP_NEAR operator for queryparser, and when I searched for "apple store" from my own collection, the query is parsed as "Zappl:(pos=1) NEAR 11 Zstore:(pos=2)" but retrieved nothing. However, if I type in "Apple Store", the query is parsed as Xapian::Query((apple:(pos=1) NEAR 11 store:(pos=2))) and some results are showed. I'm not sure whether

Hi, Xapian 1.2 supports a query like: (A OR B) NEAR (C OR D) and distributes the factors to create something like: (A NEAR 2 C) OR (B NEAR 2 C) OR (B NEAR 2 C) OR (A NEAR 2 C) Xapian 1.4 rejects such a query with the error message. OP_NEAR and OP_PHRASE only currently support leaf subqueries Because Recoll expands the terms to their stem siblings at query time, its NEAR queries

Hi all. We are trying to use Xapian to index the titles of around ten million documents (music catalogue) and then do auto-complete style search on this index. After poking around we can't quite get the combination of QueryParser flags and search query that will give back the results we want. The closest we have can take a very long time (because it is searching for, and building a list of,

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:');

Hi, I'd like to know how we can choose the distance between two words that we search in a text. I know there is an "op_near" operator but I don't know how I can specified that the number of words between the two specified words should not exceed 10 or 20 or x words. I'm really sorry for my terrible English, I hope I'm understandable!

I don?t know if the last message was with content. So, I sent again. I have installed a Digium card TE210P and unicall for use MFC/R2. I think that it?s all right but I can?t make and receive calls.

The following piece of code triggers an 'unimplemented' exception with the message: "Can't use NEAR/PHRASE with a subexpression containing NEAR or PHRASE" Xapian::Query or1(Xapian::Query::OP_OR, Xapian::Query("one"), Xapian::Query("two")); Xapian::Query or2(Xapian::Query::OP_OR, Xapian::Query("three"),

I'm happy to be able to announce that Xapian 1.3.4 is now available. Please note that 1.3.x releases are development releases - they are made to encourage earlier and wider use and testing of new and changed code. Our record with 1.1.x was very good - all the bugs I am aware of were either in new features, or were also present in the corresponding 1.0.x release. But if you main concern is

Xapians! If tomorrow Xapian search engine would achieved the same performance and result in searches as Google we would not be able to beat Google, because we would create only a copy of the searches that already exists from Google search engine. However there is a way to beat anyone, and there is a way to beat Google successfully as well just do not give up. Some see it as implementing Ajax, or

Hi, I'm the current developer of Xapian-Haystack, and I'm glad to announce that we've been finally able to install and pass all the tests of Xapian-Haystack with Xapian 1.3.3 in both Python 2 and 3, which means that Xapian-Haystack now supports Python 3. This naturally would not be possible without your efforts to push Xapian bindings to Python 3, and I thank you for that. Here I

Dear R-Help members, I have a question about how to save to the hard drive the one thousand datasets I generated in a simulation. The datasets are created in a "for" loop that repeatedly creates normally distributed datasets, such as the example below: Library(MASS) for (number in 1:1000) { dataset = mvrnorm(n = 400, mu = c(0,0,0), Sigma =
