Uses regular expression matching to find instruments

1 2	find.instrument(text, where = "anywhere", Symbols = ls_instruments(), ignore.case = TRUE, exclude = NULL, ...)

`text`	character string containing a regular expression. This is used by `grep` (see also) as the `pattern` argument.
`where`	if “anywhere” all levels/attributes of the instruments will be searched. Otherwise, `where` can be used to specify in which levels/attributes to look. (e.g. `c("name", "description")` would only look for `text` in those 2 places.
`Symbols`	the character ids of instruments to be searched. All are are searched by default.
`ignore.case`	passed to `grep`; if `FALSE`, the pattern matching is case sensitive and if `TRUE`, case is ignored during matching.
`exclude`	character vector of names of levels/attributes that should not be searched.
`...`	other arguments to pass through to `grep`

character vector of primary_ids of instruments that contain the sought after text.
