Hi everyone, I'm a bit baffled by the query syntax. Reading the manual: ``Each term in the query will be implicitly connected by a logical AND if no explicit operator is provided (except that terms with a common prefix will be implicitly combined with OR).'' I would have assumed that: term1 (tag:term2 tag:term3) would be equivalent to: term1 AND (tag:term2 AND tag:term3) but if I read carefully (and by looking at the query results), since tag: is a common prefix between term2 and term3, it is actually: term1 AND (tag:term2 OR tag:term3) am I right? Is this a feature of the xapian query syntax? (can it be tweaked to _unconditionally_ AND all terms?) For me, the idea that two terms can be ORed if the prefix is the same can cause queries to return unexpected results. What about: term1 xterm2 xterm3 term2 Is this: term1 AND (xterm2 OR xterm3) AND term2 or is it: term1 OR xterm2 OR xterm3 OR term2 ?
