Subject [Solr Wiki] Update of "SchemaXml" by JanHoydahl
Date Sun, 06 Nov 2011 21:01:14 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Solr Wiki" for change notification.

The "SchemaXml" page has been changed by JanHoydahl:

    * `multiValued=true|false`
    * `omitNorms=true|false`
    * `omitTermFreqAndPositions=true|false` <!> [[Solr1.4]]
+   * `omitPositions|false` <!> [[Solr3.4]]
    * `positionIncrementGap=N`
  
  `TextField`s can also support Analyzers with highly configurable [[AnalyzersTokenizersTokenFilters|Tokenizers
and Token Filters]].

    * Set to true to omit the norms associated with this field (this disables length normalization
and index-time boosting for the field, and saves some memory). Only full-text fields or fields
that need an index-time boost need norms.
   * `omitTermFreqAndPositions=true|false` <!> [[Solr1.4]]
    * If set, omit term freq, positions and [[Payloads|payloads]] from postings for this field.
This can be a performance boost for fields that don't require that information and reduces
storage space required for the index. Queries that rely on position that are issued on a field
with this option will silently fail to find documents.
+  * `omitPositions=true|false` <!> [[Solr3.4]]
+   * If set, omits positions, but keeps term frequencies
  
  See also FieldOptionsByUseCase, which discusses how these options should be set in various
circumstances. See SolrPerformanceFactors for how different options can affect Solr performance.
