: ...but you can't simply
: <delete><query>FIELDNAME:*</query></delete>
: or
: <delete><query>*</query></delete>
That's because the Lucene query parser doesn't support 100% wildcard
queries.
: What is the best way to delete all records, for example if you want to clear
: out the entire index and reindex everything?
if you really want to make sure *EVERYTHING* is gone -- delete the index
directory and bounce the port, solr will make a new one.
if you have a uniqueKey field, or some other field you are sure every
document contains an indexed value for, then just do an unbounded range
query on that field...
<delete><query>FIELDNAME:[* TO *]</query></delete>
