General Information

The Distributed Search provides a searchable gateway that integrates diverse geothermal resources into one location.  It accesses databases of recent and archival technical reports in order to retrieve specific geothermal information - converting earth's energy into heat and electricity, and other related subjects.

See About, Help/FAQ, Related Links, or the Site Map, for more information about the Geothermal Technologies Legacy Collection .


The Distributed Search provides you with the choice of which combination of distributed resources to search and which fields -- author, title, full record and publication date (where possible), to search.

The Distributed Search uses Distributed Explorit™, the search engine from Deep Web Technologies [exit federal site] which will "talk" to each of the search engines of the targeted resources, causing them, in turn, to query their sites or databases.  The results are returned and may include full text, bibliographic citations, and other types of material from the selected resources.

The Distributed Search utilizes the function of the individual server and database searches.  All search capabilities and options may not be available for each database.  Information on each database and a link to each site may be found by clicking on the database name on the Distributed Search page.

The resulting document titles or "hits" from your Distributed Search query will be segmented by database.  You may specify how many items you wish to have displayed from each database, up to 250.  However, there are cases in which a target database has its own rules about how many documents can be returned.  In those cases, the target's rules override the functionality of the Distributed Search.

Distributed searching, by necessity, displays the differences between databases.  It sorts your results by target resource.  This will enable you to see the differences between sites.

More about Distributed Searching

  • You decide which databases to search.
  • Remember, you can search all databases by selecting All.
  • By selecting a database link, you may view the database - you may even choose to perform your search there.
  • Then type in your key word(s) to the "Author", "Title" or "Full Record" fields (no need for quotes, we phrase-search by default), and select   search button.
  • You'll get results ranked in relevancy clusters, or grouped in a way most likely to match your search query.
  • Unlike many search engines, our results are retrieved in real time, so it could take a minute.
  • Our progress bar will time out in 50 seconds.
  • This means that if a particular database is running slow, you may not get all those results during that search session.

Not Yet Satisfied?  Try this:

  • Maybe you'd rather see your results listed by the source that sponsored the research.  Select Results by Source.
  • Now you can zero in on your area of interest.
  • You can also select More to explore deeper into each agency's resources.
  • Select the individual database or website to go directly to that site.

General Search tips

  • Full-text searching is available when supported by the agency's database.
  • You'll know the full-text PDF is available when you see the PDF icon pdf logo.
  • "And" and "Or" operators are generally supported (for example, searching drilling or logging returns results with either or both words).
  • There's no need to use quotes for phrases - we phrase-search by default.
  • Wildcard character * (asterisk) is supported in several, but not all, database (for example, geo* will find both geothermal and geology).
  • Search is not case-sensitive (for example, WELL , Well , and well will produce the same results).

More about your results

  • Results are linked to expanded information.
  • Default results are returned in QuickRank™ order.
  • Results may be displayed by Agency source, if desired.
  • Total number of search results may be restricted by the database.

Additional QuickRank™ Features

  • Our special QuickRank™ formula filters results, sending you the most relevant returns.
  • This means that the number of QuickRank™ returns may differ from the number of raw returns from the individual agency listing, which aren't filtered by QuickRank™.
  • Results will be returned in relevancy clusters: very high relevancy  indicates very high relevancy, high relevancy  indicates high relevancy, medium relevancy  indicates medium high relevancy, low relevancy  indicates low relevancy.
  • Our QuickRank™ filter is based on placement of key words:  If your key word is not in a prime location in the document, likely the result won't be ranked.
  • Your results will contain top tier databases in terms of relevancy.  But, you can also visit Results by Source  for further investigation.
