|
26. Default operator for query parsing can now be specified with q.op=AND|OR
|
|
|

|
2006-10-18 13:53:08 -04:00
|
|
|
27. New XSLTResponseWriter does server side XSLT processing of XML Response.

|
|
|
31. Support for "Date Math" relative "NOW" when specifying values of a
|
|
|
|
DateField in a query -- or when adding a document.
|
|
|
|
(hossman, SOLR-71)
|
|
|
|
|
2006-04-03 15:04:45 -04:00

|
|
Changes in runtime behavior
|
|
|
|
1. classes reorganized into different packages, package names changed to Apache
|
|
|
|
2. force read of document stored fields in QuerySenderListener
|
|
|
|
3. Solr now looks in ./solr/conf for config, ./solr/data for data
|
|
|
|
configurable via solr.solr.home system property
|
2006-09-01 15:26:31 -04:00
|
|
|
4. Highlighter params changed to be prefixed with "hl."; allow fragmentsize
|
|
|
|
customization and per-field overrides on many options
|
|
|
|
(Andrew May via klaas, SOLR-37)
|
2006-09-06 15:29:08 -04:00
|
|
|
5. Default param values for DisMaxRequestHandler should now be specified
|
|
|
|
using a '<lst name="defaults">...</lst>' init param, for backwards
|
|
|
|
compatability all init prams will be used as defaults if an init param
|
|
|
|
with that name does not exist. (hossman, SOLR-43)
|
2006-09-07 14:55:14 -04:00
|
|
|
6. The DisMaxRequestHandler now supports multiple occurances of the "fq"
|
|
|
|
param. (hossman, SOLR-44)
|
2006-10-04 14:53:06 -04:00
|
|
|
7. FunctionQuery.explain now uses ComplexExplanation to provide more
|
|
|
|
accurate score explanations when composed in a BooleanQuery.
|
|
|
|
(hossman, SOLR-25)
|
2006-11-08 19:43:54 -05:00
|
|
|
8. Document update handling locking is much sparser, allowing performance gains
|
|
|
|
through multiple threads. Large commits also might be faster (klaas, SOLR-65)
|
2006-11-27 17:40:21 -05:00
|
|
|
9. Lazy field loading can be enabled via a solrconfig directive. This will be faster when
|
|
|
|
not all stored fields are needed from a document (klaas, SOLR-52)
|
2006-04-03 15:04:45 -04:00
|
|
|
|
|
|
|
Optimizations
|
|
|
|
1. getDocListAndSet can now generate both a DocList and a DocSet from a
|
|
|
|
single lucene query.
|
|
|
|
2. BitDocSet.intersectionSize(HashDocSet) no longer generates an intermediate
|
|
|
|
set
|
2006-06-10 12:05:12 -04:00
|
|
|
3. OpenBitSet completed, replaces BitSet as the implementation for BitDocSet.
|
2006-06-10 21:15:47 -04:00
|
|
|
Iteration is faster, and BitDocSet.intersectionSize(BitDocSet) and unionSize
|
2006-06-10 12:05:12 -04:00
|
|
|
is between 3 and 4 times faster. (yonik, SOLR-15)
|
2006-06-10 21:15:47 -04:00
|
|
|
4. much faster unionSize when one of the sets is a HashDocSet: O(smaller_set_size)
|
2006-09-13 16:55:46 -04:00
|
|
|
5. Optimized getDocSet() for term queries resulting in a 36% speedup of facet.field
|
|
|
|
queries where DocSets aren't cached (for example, if the number of terms in the field
|
|
|
|
is larger than the filter cache.) (yonik)
|
2006-09-21 17:37:36 -04:00
|
|
|
6. Optimized facet.field faceting by as much as 500 times when the field has
|
|
|
|
a single token per document (not multiValued & not tokenized) by using the
|
|
|
|
Lucene FieldCache entry for that field to tally term counts. The first request
|
|
|
|
utilizing the FieldCache will take longer than subsequent ones.
|
2006-04-03 15:04:45 -04:00

|
|
2006-04-18 17:09:38 -04:00

Bug Fixes

|
|
|
2. Added escaping of attribute values in the XML response (Erik Hatcher)

|
2006-07-05 15:36:08 -04:00
|
|
|

6. Worked around a Jetty bug that caused invalid XML responses for fields
|
