--------------------------------------------------

    * This is arguably an advanced option.
    * 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 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.
+   * 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.
  
  See also FieldOptionsByUseCase, which discusses how these options should be set in various
circumstances. See SolrPerformanceFactors for how different options can affect Solr performance.
