Hi everybody, I'm the author of a small C++11 program called XDGSearch. The source code is hosted on Github, for a quick overview you can visit this link https://github.com/frank67/XDGSearch/blob/master/README.md I'm writing to the mailing list because I'd like to make the database build process splitted in more thread. Is it possible? If you are a C++ programmer you can take a look at

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

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

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

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

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

Hi, I have had a problem report from a Recoll user about the amount of writes during index creation. https://opensourceprojects.eu/p/recoll1/tickets/67/ The issue is that the index is on SSD and that the amount of writes is significant compared to the SSD life expectancy (index size > 250 GB). >From the numbers he supplied, it seems to me that the total amount of block writes is roughly

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
