Hello, I am looking for a documentation or an example to use the synonym function. I tried this db.add_synonym("omega","xapain"); and this works by adding the flag FLAG_AUTO_SYNONYMS. If i try to use the db.add_synonym("omega","xapain is search engine "); it fails why? Can xapian use synonym for Abbreviations like MBA => Master of business

I am working with version 1.2.7 and want to use stemming and synonyms. I use the perl-bindings and get some problems. First of all: the perl-bindings dont allow the QueryParser a third argument when calling parse_query! So i cannot set a default prefix (which perhaps is the solution to my problem, but later more) i have a simple testcase: 3 documents, every document only has one word:

I don't know whether this is a BUG or for special purpose... According to the definition of "xapian/queryparser.h", FLAG_AUTO_MULTIWORD_SYNONYMS contains bit of FLAG_AUTO_SYNONYMS . Therefore, long as I set the parse flag with FLAG_AUTO_SYNONYMS, the query parser will automatically activate the function of FLAG_AUTO_MULTIWORD_SYNONYMS. See the below source code part from

I am using synoyms and cannot determine how to use them in following example: $db->add_synonym('Zfoobar','Zfoo Zbar') or $db->add_synonym('Zfoobar','Zfoo AND Zbar') Or is this general not possible? MfG Felix

Hi, I'm trying to configure ssh to get this behaviour: ssh binds on "localhost:60110" and when a local application connect to that port, all the data are forwarded to the "server". The particular fact is that I can't use port forwarding because I don't have any pop3 daemon on the "server". In fact I'm using a pop3 script as user's shell! $

Very few people seem to be using synonym in Xapian, I recently found some problems in the use of synonyms. Normally, I think we should not contain any prefix info in synonym table except that 'Z'. For example, I have the following synonyms and prefix info: db.add_synonym("search", "find"); db.add_synonym("Zsearch", "Zfind");

I attempted to use the sortable_serialize function from perl, however doesn't seem to exist. The only occurrence of the string "sortable" in the /usr/local/perl/5.10.1/Search/ tree is in the pod in Xapian.pm. What am I doing wrong? use Search::Xapian; ... $doc->add_value(4,sortable_serialize($recdate)); Undefined subroutine &main::sortable_serialize called

I have an application for synonyms for tags in in notmuch, which means synonym expansion for a particular boolean prefix. I have a vague memory of Olly telling me this doesn't work, but I'm not sure about the details. My higher level goal is to support a kind of indirection with tags, where query tag:foo can really generate tag:bar or tag:fub, depending on some kind of configuration.

Hi, I know that is not possible make a stepwise procedure using REML in R, I can use ML for this. For nested design it may be very dangerous due the difference in variance structure, mainly in a splitplot design. ML make significative variables that REML dont make. I read an article that is made a stepwise procedure using GENSTAT. from article: "Terms were dropped from a model in a

We are currently in a server consolidation. We are trying to move all the Macintosh data from a G4 server to a Novell Linux Cluster. We have used Rsync to mirror the data from the Mac Server to the SAN that the Novell Linux Cluster it is using. We found that special attributes and characters did not sync. When trying another Rsync with the Novell SAN volume mounted on the Mac

There's no date defined yet, but Wheezy freeze will happen soon. How do we plan on concluding on this bug report? Recap for the actual bug I reported: If you want to start xapi, execute the following steps: 1) Start /etc/init.d/xend 2) Stop /etc/init.d/xend 3) Start /etc/init.d/xcp-xapi Step 1 is required because you need access to /proc/xen/ Step 2 is required because xapi cannot run

Which is the better way to indicating synonyms into a table? But I''d get all those synonyms together to the main table. Althought if is choosed a synonym I''d that it were directed to the object of the main table. I don''t know if a polymorphic association could be helpful in this case. Any help please? ------------- create_table :words do |t| t.string :name t.string

Hi, Using ferret and acts_as_ferret. Great work. Is there a way to define some synonyms (searchable words that would not appear in the texts ? Like stop words, but instead of being removed from query and index, they would be added ;-) Can some synonyms be regexp ? I''d like for instance to have ? (oelig) be equivalent to oe in French. Or maybe an utf8 normalization could achieve

I hope that somebody can help me with this - I think very simple - issue...? I am running a package that only accepts one line at a time, but I would like to run this package on a dataframe of >500 lines. Dataframe "d" is a single column: APPLES PEARS AUBERGINES KUMQUATS I would like to read one line of my dataframe "d", individually into a new frame "f", then

Hi List! May I tap into your combined common sense ? I have a legacy logging app that needs to be modernized. At the moment, Data is going to be stored in 5 tables, one table is going to contain more than 200 million and 2 others about 60 million rows. Mysql will be used, unless someone sees a major advantage in using something else (at the moment data is stored in a raw positioned file format,

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

I agree. There are a few gotchas, as well

After our department went to using *, I've had several inquiries about doing VoIP for my entire organization (Small county). We have ~10 locations with various links in between (Mostly p2p T1s, some Frame (1.544mbps commit), some ISDN, some VPN over 768kbit internet) Right now we're using several NEC Electra Elite systems, and 2 Nortel Meridian systems. In one of the main locations we have

Hi guys In our implementation of Xapian for one of our sites, we index the title, subtitle, summary and table of contents of around 200,000 products on ReportBuyer.com. When we create each Xapian doc to index this information, we apply a weighting to each of these 'fields' and add these to the doc using index_text with the second parameter passing in a weighting. I've been asked if

I think this is a shining example of how well Xapian works with large document collections. I was just discussing this with my colleagues here and one of the issues that came up is that we'd love Xapian to become really lot more popular but have found that the documentation's a bit difficult to get into, as is the API. So I was wondering: do you have any thoughts on improving this and
