Xapian 1.0.3 installation issues, I installed Xapian 1.0.3 and the search would not execute when run as Apache user. I could run the search fine inside ssh. I rolled Xapian to previous version 1.0.2 and the search still does not work even when I put back the old index made by Xapian 1.0.2 ... my search engine is out of work ...

Xapians, I am maintaining about two indexes for my search engines which approximately is each the same size. I would like to share this knowledge with you, since many of you have never seen Xapian index of this size. And of course you can search the index by yourself at - http://myhealthcare.com/ - http://find1friend.com/ I need 2 x 100 million more documents into each index, and I hope it will

Lately I was reading many articles about using boolean queries for search engine but I haven't seen any complete working demo. Therefore I put together very simple working demo of search engine using boolean query. Feel free to suggest any performance improvement or error while keeping it as simple as possible for understanding. Thanks, -Kevin Duraj http://myhealthcare.com

Hi, I am looking for Chinese Japanese and Korean tokenizer that could can be use to tokenize terms for CJK languages. I am not very familiar with these languages however I think that these languages contains one or more words in one symbol which it make more difficult to tokenize into searchable terms. Lucene has CJK Tokenizer ... and I am looking around if there is some open source that we

I''ve been looking into RESTful approaches lately. Everything I know my dog, Lelu, taught me. REST (REpresentational State Transfer) is an architectural technique for networked applications first described by Roy Fielding in his dissertation at UC Irvine-- excellent work, especially considering the tempting proximity of Newport Beach. As Lelu described it to me, REST strives

Xapians! Did anybody wrote and would like to share a routines that parse result from doc.get_data() into some key and pair values in C++ ? Code: Xapian::Document doc = i.get_document(); string data = doc.get_data(); mymap = parse_result(data); As you know the data string contain all the data within the document delimited by "=" sign and "\n" new line and needs to be parse

Dear All, Does anyone use S or R for statistical natural language processing (NLP)? All I have found so far is a package called EMU (http://www.shlrc.mq.edu.au/emu/emu-splus.shtml) which is a speech wave-form processing package. What I'm looking for are routines to support text processing, text categorization, word sense disambiguation, text understanding etc. In particular, I would

There is is bug when setting XAPIAN_FLUSH_THRESHOLD=20000000 When trying for force Xapian flush documents to flush after 20 million documents Xapian ignores the size and flush it after only 10,000 documents. Data captured from delve after 60 seconds interval when has been set as follow: XAPIAN_FLUSH_THRESHOLD=20000000 perl -e ' while(1) { system("delve ."); sleep(60); } '

Luke, I thought about what you said about nouns, but having trouble coming up with an example of what you mean. Would you be willing to rework my example into the words your talking about? I''m not asking for a solution here...this is more about how to think about the problem being solved. Mike B. ---------------------------------------------------------------- This message was sent

Hello, I was wondering if anyone has succeeded in getting the Java bindings to work with NetBeans, in order to make use of NetBeans's GUI developer. I've had no luck so far, does anyone know how to do that? Many thanks.

Hi all, I know this is a long shot, but could renaming the "Journey" module please be considered by those in a position to support it? I''ve written an issue on this in the journey repo also: https://github.com/rails/journey/issues/49 Essentially our project has a model named Journey, the same as Rails 3.2''s new routing driver. As a consequence we can no longer

Hi, While trying to setup xapian replication (initially for backup purposes), I'm encountering some errors. Our "fresh" index starts replication, and ends up with an index size that matches the replication master (4.5GB), but then throws : "Getting update for fresh from fresh xapian-replicate: NetworkError: Unable to fully synchronise: Database changing too fast" I

People, I have an insurance company client and for the last eleven years I have wanted to completely redevelop their system from scratch. However, the boss has never been interested in hiring a team to develop the new system (partly because of the cost and partly because of some famous and expensive development failures in the industry) and has always insisted on incremental development of the

Flint failed to deliver indexing performance to Quartz. I am proposing to remove Flint as default database and place Quartz database back as default. The catch is not that Flint database is smaller and faster during searches then Quartz database as developers were concerning when were measuring and neglecting to measure performance when creating the large indexes. The truth is that Flint

Greetings! I''m thinking of setting up a table of "domains", consisting of the core fields id, code, name, description, and type. Users is a domain, orders is a domain, recipes is a domain, etc. Domain attributes other than those covered by the core fields will go to, say, a user_other_fields table, recipe_other_fields, etc. I see the advantage of having all

Hi all, A few of us have been discussing whether we should have a Xapian social gathering of some kind. The current idea is meeting up in a pub in London some time in autumn for drinks and food. However all of this really depends on who might be able to come! It would be a chance to meet other Xapian enthusiasts in an informal social setting and talk about all things search-related (and
