--------------------------------------
Hi Laurent,
Thanks for your interest in my Solr PayloadComponent plugin. I want to
address all of the questions you pose in your comment, but won't have time
until early February. I apologize for the inconvenience but my priorities lay
elsewhere right now. Feel free to look at the code and play in the meantime.
The code that's up there is basically proof of concept. I've been slowly
working at improving the robustness of the code and improving performance so
hopefully there will be a improved version before the end of March.
I'm sure there would be many people who would appreciate a Wiki page for
this topic. Why don't you go ahead and set that up? I'll be happy to add my
two cents when I'm available.
All the best,
Tricia

> "Paged-Text" FieldType for Solr
> A chance to dig into the guts of Solr. The problem: If we index a monograph
> in Solr, there's no way to convert search results into page-level hits. The
> solution: have a "paged-text" fieldtype which keeps track of page divisions
> as it indexes, and reports page-level hits in the search results.
> The input would contain page milestones: <page id="234"/>. As Solr processed
> the tokens (using its standard tokenizers and filters), it would concurrently
> build a structural map of the item, indicating which term position marked the
> beginning of which page: <page id="234" firstterm="14324"/>. This map would
> be stored in an unindexed field in some efficient format.
> At search time, Solr would retrieve term positions for all hits that are
> returned in the current request, and use the stored map to determine page ids
> for each term position. The results would imitate the results for
> highlighting, something like:
> <lst name="pages">
> <lst name="doc1">
> <int name="pageid">234</int>
> <int name="pageid">236</int>
> </lst>
> <lst name="doc2">
> <int name="pageid">19</int>
> </lst>
> </lst>
> <lst name="hitpos">
> <lst name="doc1">
> <lst name="234">
> <int
> name="pos">14325</int>
> </lst>
> </lst>
> ...
> </lst>
