I am making some modifications to the way Lucene works with Cocoon, and am wondering if you lot think these modifications are suitable to add to the 2.1 CVS.
1.) Allow the 'query' to be set on the SearchGenerator from the Sitemap. (Currently, it only reads the query directly from the request, setting via the sitemap overides this)
WHY?: because you can do lots of funky things like modify the query on the fly by manipulating sitemap params directly or via an Action. This is useful for things like security (not allowing certain docs to become hits to certain users), partitioning (searches of only part of a site), search wizards (helping to build complex searches) etc.
Ok
good
And may be handling of some other parameters can be changed too.
I would love to make this configurable, but do not know how.2.) Modified LuceneIndexContentHandler to add (Stored, Untokenised, Unindexed) 'title' fields to the index, made from
Configurable (and default is<title/>)
Any suggestions would be gratefully accepted!
Can't help right now... Come up with something ;-)
tags in the content.
WHY? So that you get the title(s) of your documents with the search hits!
Merits:
mod 1 has no impact on anyone using Lucene as it is today, as the old mode of operation is not effected.
mod 2 _does_ have an impact on the way Lucene works, if you have lots of <title> tags in your document, you will get all of them displayed in your hits. If there are too many for your taste, you would need to pre-filter your content, using a stylesheet in the 'content-view' to simplify your docs before they get indexed.
IMHO, this is a good thing to do anyway!!
thanks for any input ......
The next modification I am planning is to allow the re-indexing of single documents .....
Isn't it already possible by using "update index"?
While playing with Lucene, I find no time difference between 'create' and 'update'.
I believe update index still uses the crawler to get the content, meaning that a well-linked site will end up getting totally reindexed.
Are you referring to *sample* create-index.xsp page? But this is *sample*! :)
AFAIU, You can extend it to behave more like Cocoon CLI: option to crawl or not to; not one input URL, but set of URLs, etc.
