Number of bytes = (15+L)*U + U*PAGESIZE * R +
T
where:
- L = average term length for the
vocabulary
- U = number of unique terms in the
vocabulary
- R = number of millions of
documents
- T = total number of all terms in all
documents
The temporary space required in bytes for the TEXT index is (M+20)* T,
where:
- M = the maximum term length for the
text configuration in bytes
Note: The temporary space required is subject to compressibility
of the sort data.
