The Instant Search integration section is incorrect

Custom search for particular fields is accomplished using the
'search_in' parameter instead of the 'field_selector'
The 'search_in' variable w/in the Filter.js is also misspelled and
should be corrected
Misspelled Word
Initialize the filter with the "min-length" option specified

min_length:
Inspired by the "minLength" option in the Autocomplete Widget, the
"min-length" specifies  the minimum number of characters a user must
type before a search is performed.
"1" is the default value and is useful for local data with just a few
items, but a higher value should be used when a single character search
could match a few thousand items.
Corrected the documentation for min_length

min_length instead of min-length
