<br>
<font size="2" face="sans-serif">However, you can't search on the - character. Currently, it's only possible to search like this: datestamp:(2008*) but not datestamp:(2008-02*) or datestamp:(2008-02-11*) or with double quotes.</font><br>

for author searches, don't put the names into double quotes, but into brackets:</font><font size="3" face="serif"><br>

I have two questions on research Xapian :<br>

1. How query the fields : datestamp ?<br>

2. How query the fields : creators_name (name_family with name_given ) ?<br>
<br>
<br>
<br>
We added fields (datestamp and creators_name) in the file cfg.d/eprints_search_simple.pl and reindexed the database.<br>
$c->{search}->{simple} = <br>

search_fields => [<br>
