Hi, I have a user reporting the following error during recoll indexing: flush() failed: Db block overwritten - are there multiple writers? "flush() failed" is from recoll, the rest is, I think the text of the Xapian exception. This is with Xapian 1.4.3 on Linux (I asked for more details, should be coming). I don't think that I've ever seen this error, and I also

A Recoll user gets the following message while indexing: "Attempted to delete or modify an entry in a non-existent posting list for #bannerholder" The exception happens during a commit call. Xapian version 1.4.11, Debian Buster A little more detail here: https://opensourceprojects.eu/p/recoll1/tickets/108/ I asked if this was reproducible, and to run the indexing in single-thread

Hi, I have had reports that Recoll has become unbearingly slow in some instances. After inquiry, this happens with Xapian 1.4 only, and the part which does not work any more is the snippets extraction. Recoll builds snippets by partially reconstructing documents out of index contents. For this, after determining a set of document term positions to be displayed (around the hopefully interesting

Hi, While investigating very infrequent crashes in the Recoll indexer, I have come to a very basic question: is it safe to pass a copy of a Xapian::Document from thread to thread (multiple threads queue documents, other thread updates the index) ? I don't seem to get directly into trouble while doing this, but I don't see anything either in the RefCntr implementation which would

People, I sent this note to JF at Recoll and he suggested asking here (his response below) - any suggestions?

Hello, I am hearing of users having trouble linking with libxapian (on slackware and gentoo systems, and 0.9.2 I think), and I am not too sure where the problem comes from, or what the correct solution could be, so I am just asking here in case someone has a quick answer. What happens is that "xapian-config --libs" outputs libstdc++.la in the list of libraries. Something like:

Hi, A Recoll user is reporting an index corruption problem. In general, index corruption happens from time to time with Recoll, because of crashes, reboots, misc Recoll bugs, etc. The strange thing here is that xapian-check does not seem to detect anything. In a nutshell, some document numbers seem to point to a data blackhole: the docids are returned when searching for the file/doc unique

Dear senior ML members and developers of Xapian Omega, Mr. Olly has helped me cross the bump of the initial learning curve. (ref: https://lists.xapian.org/pipermail/xapian-discuss/2024-April/010034.html) How can I use Xapian Omega directly (i.e., without using `recoll` and `xapiandb`) to index a directory of text files with all strings greater than 3 characters, to create an index text file

I seem to be seeing cases where I call db.delete_document(somedocid) with no error, then flush() and delete the database object, but the document is still there after process exit. The write lock is normally deleted, so it appears that the database close finished normally. If I then then call delete_document(somedocid) from another command/process, this time it goes away. I've been seeing

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
