Description: This document contains Solr 4.x schema definition to
be used with Solr integration currently built into Nutch.
This schema is not minimal, there are some useful field type definitions left,
and the set of fields and their flags (indexed/stored/term vectors) can be
further optimized depending on needs. See
http://svn.apache.org/viewvc/lucene/dev/trunk/solr/example/solr/conf/schema.xml?view=markup
for more info.

Numeric field types that index each value at various levels of precision
to accelerate range queries when the number of values between the range
endpoints is large. See the javadoc for NumericRangeQuery for internal
implementation details.
Smaller precisionStep values (specified in bits) will lead to more tokens
indexed per value, slightly larger index size, and faster range queries.
A precisionStep of 0 disables indexing at different precision levels.

is a more restricted form of the canonical representation of dateTime

The trailing "Z" designates UTC time and is mandatory.
Optional fractional seconds are allowed: 1995-12-31T23:59:59.999Z
All other components are mandatory.
Expressions can also be used to denote calculations that should be
performed relative to "NOW" to determine the value, ie...
NOW/HOUR
... Round to the start of the current hour
NOW-1DAY
... Exactly 1 day prior to now
NOW/DAY+6MONTHS+3DAYS
... 6 months and 3 days in the future from the start of
the current day
Consult the DateField javadocs for more information.

matching across fields.
