Specialized Search Services
So far, your searching experiences have been with general-purpose directories and search engines. There are others that are designed to index
or search for specific topics and services.
Recall that even the search service with the largest database only indexes, at best, half the documents on the Web. A directory or search
engine that is specialized will have a smaller database, but one that may very well return more relevant information in its field than its
larger general counterparts.
What follows are just a few examples of specialty search services. You can search for more or use the searching resources from earlier in
this module to locate others. As you look through the list, take a minute or two to tour the ones that may be of use to you as a possible key
site or other part of your searching strategy.
Topic-specific directories and search engines
In addition to these, you can search for topic-specific results in education, medicine and health, reference and career and job search

The information in services like these comes from public records and data sold by companies. They will vary in how up-to-date their information remains, and unlisted telephone numbers are not usually available.
In addition to the examples below, a search will turn up some counties' jail records, genealogy databases, unclaimed bank accounts, and death records.
