Usually, people want to do the opposite - store the numeric code as a
numeric field for perceived efficiency and let the user query and view
results with the text form. But, there isn't any evidence of any great
performance benefit of doing so - just store the string code in a string
field.
Also, your language is confusing - you say "a single integer field that maps
to the string field" - do you actually want two separate fields? Is that the
case? If so, just let the user query against either field depending on what
their preference is for numeric or string codes.
And your language seems to indicate that you want the user to query by
numeric code but the field would be indexed as a string code. Is that the
case?
Maybe you could clarify your intentions.
Sure, with custom code, custom fields, custom codecs, custom query parsers,
etc. you can do almost anything - but... the initial challenge for any Solr
app developer is to first try and see if they can make due with the existing
capabilities.

You seem to know what you want the words to map to, so index the map. Have
one field for the word, one field for the mapped value, and at query time,
search the words and return the mapped field. If it is comma separated, so
be it and split it up in your code post search.
Otherwise, same as Wunder, in my many years in search this is an odd request

What are you trying to do? This seems really odd. I've been working in
search for fifteen years and I've never heard this request.
You could always return all the fields to the client and ignore the ones you
don't want.

can someone point me to a "custom field" tutorial.
i checked the wiki and this list - but still a little hazy on how i would
do
this.
essentially - when the user issues a query, i want my class to interrogate
a
string field (containing several codes - example boo, baz, bar)
and return a single integer field that maps to the string field
(containing
the code).
example:
boo=1
baz=2
bar=3
thx
