Lucene, Nutch and Solr

Hi

I've been looking for times for a system to do my project :
It is an event search engine. Quite common thing.
But here in France, very few event sources have rss, xml, or anything that
permit event syndication.

Here's the idea : index given websites, or even scan paper programs with
OCR, input into the engine,
And it sorts out itself what is the start date, end date, where the event
takes place (city name), The title and the description of the event.
Then it makes a list out of these events for people to go out.

Mathematic Arts is a Drupal development firm in Milwaukee. We recently developed a web site for a research library in Drupal 7, and implemented Solr and Nutch for the search facility. We are using Facet API to filter search results based on a few simple criteria, but would like to do some more complicated filters and to improve the user experience.

For example:

• Have a facet like content type, but that aggregates many of the general content types that are meaningless to a user. For example:

Thanks in large part to the talented Nick_vh who is interning with Acquia as the final stage of his master's degree, we've been making progress on a number of outstanding issues for apachesolr 7.x. If you are using the module, please take a look at http://drupal.org/node/1293570 which lists remaining issues to be included in the next beta release (possibly the end of this week).

The patch to improve custom search pages includes a number of re-arrangements for the UI, so please try it out: http://drupal.org/node/1294846

I am using Apachesolr module with Drupal 6. I have only one facet so far on my searching and that is the node type. I have a list of links that is supposed to filter the query. When I put in a search term, I get all the matching results and the list of links with the correct counts for each node type. However, when I click a node type it returns just the result for that node type, but now all the counts in my link list have turned to 0, except for that node type which shows the correct amount, I have it set a $_REQUEST['filter'] parameter.

I have a site that is based on Open Atrium and currently using solr for site search. I would like to be able to add organic group members to the search index so that I can search for users within a particular OG. I would appreciate suggestions on how best to approach this.

Solr is set up via the Chapter 3 open atrium features module here http://features.chapterthree.com/openatrium-apachesolr-search/1-0-0, which uses apachesolr, apachesolr_og, apachesolr_search, and apachesolr_nodeaccess. In addition, Open Atrium uses nodeprofile so users' profiles are already in the index.

What I have considered doing is adding users' profile nodes to the same groups that they belong to. This would then make them searchable by OG, however my concern is that I would like everyone to be able to search for users across all OGs, including private OGs, and this would result in permission issues.

I would really appreciate any suggestions. Thanks.

The Problem

The search community is fragmented. The problem stems from a core search module that doesn't facilitate third party backends, so each project is forced to solve similar problems in slightly different ways. Each contributed module has its own isolated sub-community, which is detrimental to Drupal as a whole.

We have a website which is mostly English, but some of the fields in some of our content types are in another language. This other language has different rules for alphabetization, etc. We'd like to be able to sort searches on these fields using the appropriate locale.

You can do this in the Solr schema.xml file by adding the appropriate locale="..." attribute to the field definitions. I'm wondering whether there's a way to do this through the Drupal API, so that we don't need to modify the schema.xml file. Has anyone else looked into this idea?
