E.9 Estimating Hybrid Search Trace Information Disk Space Requirements

The bulk of the size of the hybrid search trace information is the text chunks that are the search results.

Describes the formula for estimating the amount of text chunks recorded per hybrid search.

Total size of text chunks recorded per hybrid search = average size of text chunks x (n_0 + n_1 + n_2)

n_0: Number of hybrid search returned

n_1: Number of semantic text search returned

n_2: Number of full-text search returned
