> "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">
> &nbsp;&nbsp;<lst name="doc1">
> &nbsp;&nbsp;&nbsp;&nbsp;                <int name="pageid">234</int>
> &nbsp;&nbsp;&nbsp;&nbsp;                <int name="pageid">236</int>
> &nbsp;&nbsp;        </lst>
> &nbsp;&nbsp;        <lst name="doc2">
> &nbsp;&nbsp;&nbsp;&nbsp;                <int name="pageid">19</int>
> &nbsp;&nbsp;        </lst>
> </lst>
> <lst name="hitpos">
> &nbsp;&nbsp;        <lst name="doc1">
> &nbsp;&nbsp;&nbsp;&nbsp;                <lst name="234">
> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;                        <int
name="pos">14325</int>
> &nbsp;&nbsp;&nbsp;&nbsp;                </lst>
> &nbsp;&nbsp;        </lst>
> &nbsp;&nbsp;        ...
> </lst>
