Subject: Lucene search indexes
To: [email protected]
Hi, I am using DSpace 1.6 and am trying to create some specific indexes and
use them via the query box. So for example I define an index in the
dspace.cfg file as :
search.index.13 = indexname:dc.element.qualifier
where dc.element.qualifier is replaced by my metadata field name. Now in the
query string I can refer to this index by the syntax:
indexname:xxxx
This works OK when the metadata field containes strings. However I need some
to be integers and floating point values, so I can refer to them in range
statements such as:
indexname:[1.3 TO 5.6]
When I put floating point values in the metada fields and try the lucene
range statement query syntax it gives unexpected results. it finds the items
sometimes when the value is outside the range and sometimes when it is
inside the range depending on what the range values are.
Now I saw in the codebase that the search.index.n syntax allows a type entry
such that the following sahould create a floating point index field:
search.index.13 = indexname:dc.element.qualifier:float
However this does not work as expected as the range statement does not
return the correct items as per range values. Can anyone say what I am doing
wrong, or not understanding.
