Hi,
It's unclear... found in schema.xml:
omitNorms: (expert) 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.
termVectors: [false] set to true to store the term vector for a given field.
When using MoreLikeThis, fields used for similarity should be
stored for
best performance.
Questions:
omitNorms: do I need it for full-text fields even if I don't need
index-time boosting? I don't want to boost text where keyword repeated
several time. Is my understanding correct?
termVectors: do I need it for MoreLikeThis only?
What are memory requirements for Lucene caches warming up if I use
term vectors and norms?
Thanks,
Fuad
