similar to: OP_ELITE_SET and max number of terms

In current Xapian SVN HEAD, there is a bug in the query parser concerned with the handling of wildcard terms with a "+" prefix. Specifically, a query such as "+foo* bar" will be parsed by the query parser into Xapian::Query("bar") if there are no terms in the database which start "foo". Instead, since the "+" term cannot be matched, I believe

Hi R users. sorry for missing example and if question is to general but I am wondering if it is possible to execute subqueries in function sqlQuery (package RODBC) with opened connection with Excel or SQL server 2000. I couldn't find any example of this. And if it is possible what should be a correct syntax for this query: SELECT ct,COUNT(*) as n FROM (SELECT COUNT(*) AS ct FROM children

Good afternoon I would like to ask if is possible somehow give more relevance to the recent documents in search results. I dont want to sort results according to the date, I still prefer relevance, but I would like to see recent documents with better scoring. I was trying to add search query using AND_MAYBE, which should use relevance from both subqueries, but it didnt add any benefit to the

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

Dear R users, I would like to know if there is a way to increase the for() loop speed because in my routine the calculations are too slow. Best regards.

How to plot multiple variables on the same graph Dear R users, I want to plot the following variables (a, b, c) on the same graph. The x-axis must be the variable mat and the graph must have the type = "l".

I'm replying to a very old thread (9 years ago) here http://grokbase.com/t/xapian/xapian-discuss/072tprmr6h/php5-query-parsing-bug So not sure if that's going to end up being more or less readable... I have this error : Fatal error: No matching function for overloaded 'new_Query' in /usr/share/php/xapian.php on line 2607 Line 2607 (and surrounding) looks like this and are in

I have one table that stores data related to math problems, and another table that stores users'' answers to those problems. To make this very simple, we''ll say that the math table has two numbers that get subtracted, and the answers table has a field that can either be "pos" or "neg" math _____ 2 5 8 3 Okay so if we do the math, we know that the

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

Hello R-USERS, I think some people didn't understand my question. What I want is to use the training set to minimize the FALSE POSITIVE RATE. I think it is possible. I sacrifice ACCURACY to have less FALSE POSITIVES. I don't want a classifier result with 5% of FPR and, for example, 93% of ACCURACY. I want a 1% FPR sacrificing the 93% ACCURACY. Do you know how can I do this? I really
