Search Designation-Systems.Net

Two free site search engines are offered:


This service uses the standard Google search engine, restricting the results to pages in the domain Designation-Systems.Net. Google's update cycle is about 4 to 8 weeks, so the most recent content cannot be found with this engine. Google allows phrase search, which makes it a useful tool to search for designations like e.g. "EP-3E". Refer to Google for further Search Tips.

This service is powered by the FreeFind site search engine. The Designation-Systems.Net website will be re-indexed about once a week, so the search results should be reasonably up-to-date. This site uses the free version of FreeFind's service, so the result pages will have some ads on them. See paragraphs below search box for search tips.

The following box is a copy of FreeFind's "Search Tips" page:

By default the search engine tries to locate pages which have exact matches for all of the words entered in your search query. If that fails, it then tries to locate pages which contain any words in your search query. If that happens a short message is displayed at the top of the search results indicating this has been done.

In addition, there are several ways to modify the default search behavior.

  1. phrase search
    The search engine supports three types of phrase search.
    • To match an exact phrase, use quotes around the phrase
      Example: "free search engine"
    • To match a near (within a couple of words) phrase, use square brackets [around the words]
      Example: [free search engine]
    • To match a far (within several words) phrase, use braces { around the words }
      Example: {free search engine}
  2. + and - qualifiers
    If you prepend a word with + that word is required to be on the page.
    If you prepend a word with - that word is required to not be on the page.
    Example: +always -never
  3. * wildcard
    If a query word ends with a * all words on a page which start the same way as that query word will match.
    Example: gift*
  4. ? wildcard
    If a query word contains a ? any character will match that position.
    Example: b?g
  5. boolean search
    You can use the following boolean operators in your search: AND, OR, NOT. These operators MUST be in capital letters.
    Example: (contact AND us) OR (about AND us)
All of these techniques can be combined: +alway* -ne??r*

The usefulness of FreeFind's automatically created Site Map is limited, at best ;-).
