Shay Rojansky 7d7a6494e5 .Net: [MEVD] Implement support for score threshold (#13501)
For providers which don't natively support score threshold, I've gone
with applying the filter client-side - the other option would be to
throw.
* In EF we're quite strict on not bringing back database data in order
to client-evaluate; in other words, if the user wants to load database
rows from the database and then perform some post-filtering, they need
to write that explicitly in code, to avoid scenarios where tons of data
gets unintentionally transferred.
* In MEVD we already implement Skip in various providers by bringing
back the entire matching resultset and then filtering client-side. This
is potentially much worse than filtering for score threshold
client-side, as the amount of extra data brought back by threshold
post-filtering is limited to top (k), whereas with Skip/pagination
queries that amount of data grows with each page.
* Ultimately, MEVD is simpler and more high-level, and is also
explicitly designed for layers to be composed on top (e.g. MEDI). So
there does seem to be more value in features "just working" across
providers.
