The admin UI>>(select a core)>>analysis page is your friend here. It'll
show you exactly what each filter in your analysis chain does and from
there you'll need to mix and match filters, your tokenizer and the like
to support the use-cases you need.
My guess is that the field type you're using contains
WordDelimiterFilterFactory which is splitting up on the slash.
Similarly for your aribag/airbags problem, probably you have
one of the stemmers in your analysis chain.
See "Filter Descriptions" in your version of the ref guide.
And one caution: The admin>>core>>analysis chain
shows you what happens _after_ query parsing. So if
you enter (without quotes) "bing bong" those tokens
will be shown. What fools people is that the query _parser_
gets in there first, so they'll then wonder why
field:bing bong
doesn't work. It's because the parser made it into
field:bing default_field:bong. So you'll still (potentially)
have to quote or escape some terms on input, it depends
on the query parser you're using.
Best,
Erick
