Re: does solr have a mechanism for intercepting requests - before they are handed off to a request handler
Why not wrap the call into a service and then call the right handler?

Re: does solr have a mechanism for intercepting requests - before they are handed off to a request handler
I'm doing something like that by hacking SolrRequestParsers, I tried to find more legal way but haven't found it http://mail-archives.apache.org/mod_mbox/lucene-dev/201202.mbox/%3CCAF=Pa597RpLjVWZbM=0aktjhpnea4m931j0s1s4bda4qe+t...@mail.gmail.com%3E I added solrRequestParsers into solrconfig.xml https://github.com/m-khl/solr-patches/commit/f92018818b20d79b01d795f2c52446b499023dd8#diff-4 Also, have you considered j2ee's webapp servlet filters?

Brilliant, thank you, that LukeRequestHandler looks very useful. On 10/4/07, Erik Hatcher [EMAIL PROTECTED] wrote: 3. Is it possible to change stopword and synonym sets at runtime?

I'll expose my confusion here and say that I don't know for sure, but I'm pretty sure that once it's been loaded it won't get reloaded without bouncing Solr altogether. solr-dev's, please correct me with some code pointers if I'm wrong. In my brief IntelliJ surfing this morning, it seems that once a SolrCore has been instantiated, that instance sticks around forever, and it holds the IndexSchema instance. I'm guessing that the new multi-core stuff makes this a bit more dynamically controllable. Is changing the underlying file while Solr is running dangerous? No - it only reads it once as far as I can tell. Caveat to all technical details above: I'm still learning the ropes with the core of Solr so if I misspoke on any of this lifecycle stuff, let me know. By trying to answer questions, though, I learn quicker :) Erik

dooh, should check all my email first! Will Solr automatically reload the file if it changes or does it have to be informed of the change? I'll expose my confusion here and say that I don't know for sure, but I'm pretty sure that once it's been loaded it won't get reloaded without bouncing Solr altogether. Correct. The StopFilterFactory is initialized at startup, any changes to the file won't take effect 'till solr restarts. but you can write a custom FilterFactory based on StopFilterFactory that lets you change it dynamically. Most likely this would also require writing a custom RequestHandler to manipulate it. note - changing the stop words at runtime will only effect queries, the index will keep whatever was there at index time. ryan

Re: Does Solr Have?
How does one set up the LukeRequestHandler? I didn't see a document in the wiki about how to add new handlers, and my install (a 1.1 install upgraded to 1.2) does not have this handler available. I'd like to see what we're talking about, it sounds very interesting.. but I can't find how to turn on this request handler. ++ | Matthew Runo | Zappos Development | [EMAIL PROTECTED] | 702-943-7833 ++ On Oct 4, 2007, at 6:11 AM, Ryan McKinley wrote: Robert Young wrote: Hi, We're just about to start work on a project in Solr and there are a couple of points which I haven't been able to find out from the wiki which I'm interested in. 1.

Re: Does Solr Have?
: Is there, or are there plans to start, a plugin and extension repository? Strictly speaking, there is no reason why Solr Plugins would have to live in an Apache repository. if people write plugins that would be generally usefull to several people, and they wish to contribute them to Apache, they can be commited into the Solr repository -- but people could also host/distribute a plugin on some other site (sourceforge, etc...) however they see fit (using pretty much any license they see fit, i believe). If people start doing that, then we should definitely have anice wiki page for people to list those things. Note: there was another thread recently on solr-dev about adding a contrib section to the solr repository and bundling them in individual jars as an alternative to including them in the core solr.war... http://www.nabble.com/Solr-contrib-tf4517606.html#a12886773 -Hoss
