Ted,
It seems that what you need is a QDA software (Qualitative Data
Analysis). I wrote such a software (QDA Miner) but it is a commercial
one. See:
www.simstat.com/QDAMiner.htm
The free trial version can handle thousands of documents but allow
classification of only the first 25. Most QDA software will allow you to
assign one or multiple codes to whole units of text or only selected
segments. They will also allow text retrieval, searching, comparison, based
on the codes assigned manually.
There are several other QDA software available on the market including some
freeware. You can read a comparative review of the most popular ones and
get links from:
