searching large sequences against funfam produces error

[sillitoe]

Searching UniProtKB sequence Q7Z589 (1322 residues) against FunFams produces an error.

This is due to the results object being too large to be stored by memcache.

Possible options:

• limit the number of hits stored in the results object
• make the results object more efficient
• move data store away from memcache

Changes:

• max FunFam records now limited to top 50
• result object made more efficient (ie smaller data structure):
  • do not store hsp strings by default
  • store floats to %.2d (2 dec. places)
• will keep data store as memcache for the moment (but investigating elasticsearch)

In this example (Q7Z589), the issue was not the number of hits since this actually returned zero matches against the FunFams.

The issue of bloated data structures was causing issues with other large query sequences though. Seems to have improved response times.
