Implicit parser specification

[zgornel]

The ability to select parser or parsing modes from a given text - i.e. parser detection stage (with default must exist)
In the request, the preparser should have a similar name i.e. pre_parser
This parser should access all available parsers

Examples:

• noop> text noop mode, text is the actual query sent to db, searchers
• nlp> some thext that can be nlp'd NLP mode
• imp> https://julialang.org/v2/img/logo.svg` image mode
• db> col1:value AND col2:[min, max]` juliadb mode
• index> "index_1":"something embeddable" specify index and some text that the embedder of a searcher will recognize (i.e. simple text, a link to an image etc)

Ideea:
whatever query is sent gets triaged by an initial pre-parserthat looks for the pattern r"[a-zA-Z]+>"
and if found, selects the parser. A default has to exist, most probably noop_parser
