Description:
In v15.5 we were able to do searches with the words in quotation and get phrase search results. In v17 this is not working. tab11_word and tab_word_breaking are set up exactly the same in the 2 versions. The only difference is that we changed ADJACENCY_TYPE from 2 in v15.5 to 0 in v17. It was our understanding that this would only effect indexing and response times, not functionality.

Why doesn't putting a search in quotation marks return phrase search results?

Examples:
wrd=wild !0 rice - 18 hits
wrd=wild %0 rice - 18 hits
wrd="wild rice" - 19 hits
wrd=wild rice - 19 hits

wrd=popular !0 reading - 305 hits
wrd=popular %0 reading - 306 hits
wrd="popular reading" - 332 hits
wrd=popular reading - 332 hits

Resolution:
In v16-up, adjacency_type 0 does not work: when the Words are built with adjacency_type 0, putting the search in quote marks does not work.

You should always specify adjacency_type 2 in version 16-up.

The documentation for adjacency_type 0 has been changed as follows:

Note! It is highly recommended NOT to use this type of adjacency. The adjacency is kept only for backwards compatibility (for converting libraries that built their indexes in previous version).
