Proximity searches
You can specify the number of nonsearch words that can occur between search terms in a proximity search.
To perform a proximity search, enclose the search terms within
double quotation marks and append a tilde (~) followed by the number
of nonsearch words allowed. For example, to search for the terms
curb
and lake
within
8 words of each other within a document, use the following search
predicate: bts_contains(column, ' "curb lake"~8 ')
