Inconsistent behavior in faceted search with "wrong" capitalization

[dimus]

Uninomial search allows lowcase: "uni:algae" finds "Algae C. Linnaeus, 1753" from development db.

genus, species, author, susbspecies do not find records with wrong capitalization.

We need to make it consistent, lets decide what is better to ignore capitalization everywhere in name_string?search_term or not.

[alexander-myltsev]

The reason why uni:aglae passes is that every search is first-letter capitalised before execution. We should discuss what kinds of searcher should be case agnostic.

Exact modifier: search as-is (even 2-or-more white spaces)

Canonical (+ wildcard): clean query ~> make capitalisation (if first two chars are not x<space>)

NameString:

• search over name only (omit canonical match)
• invariant of capitalisation, spaces, unicode

Genus, species, author, subspecies, year: capitalisation, spaces, unicode invariant search

No-modifiers:

• wildcard less: parse name ~> (ns: + match over canonical)
• wildcarded: don't parse name ~> full text search over DB
