• If you get too many junk or nonsense answers, try:
1. Add some more words to your query.
2. Decrease the range of the Proximity control.
3. Change the Word Forms control to Exact.
4. Look at the Match Info and see why they are showing up.
5. Use the Exclusion Operator (-) to remove unwanted terms.
6. If you are searching for a phrase, hyphenate the words together.
• If you don't get any answers, or just too few:
1. Remove some more words to your query.
2. Examine your spelling.
3. Increase the scope of the Proximity control.
4. It just might not be there?

• Controlling proximity:
  Mastering the usage of proximity gives the ability to locate answers with greater precision. The Site Search input form gives you several options to control the search proximity:
• line
  All query terms must occur on the same line
• sentence
  Query items should all reside within the same sentence
• paragraph
  Within the same paragraph or text block
• page (default)
  All items must occur within same HTML document

The bar-graph display ( ) will be shown any time a ranking search was performed (eg. all searches except Show Parents). More blue indicates a better match.

• Ranking Factors
  The ranking algorithm takes into consideration relative word ordering, word proximity, database frequency, document frequency, and position in text. The relative importance of these factors in computing the quality of a hit can be altered under RANKING FACTORS on the Options page.
• Keywords Phrases and Wild-cards:
  To locate words, just type them in as you would in a word processor. Letter cases will be ignored.

The wild-card character * (asterisk) may be used to match just the prefix of a word or to ignore the middle of something.

To locate a number of adjacent words in a specific order, surround them with " (double quotation) characters. Putting a '-' (hyphen) between words will also force order and one word proximity.

Examples:

• Applying Search Logic
  Texis and Metamorph use set logic for text queries. Set logic is easier to use and provides more abilities than boolean. The examples below make reference to single keywords, but keep in mind that each keyword can represent an entire list of things or any of the special pattern matchers.

  Sets (or lists) of things are specified by placing the elements within parenthesis, separated by commas. example: (bob, joe, sam, sue). In the examples below, you could replace any of the keywords with a list like this.

  The default behavior of the search is to locate an intersection (or 'AND') of every element within a query. This means that the query; "microsoft bob interface" is the equivalent to the boolean query: "microsoft AND bob AND interface"

  • '-' (without)
    The '-'(minus) is the most commonly used logic symbol. It means the answer should EXCLUDE references to that item.
  • '+' (mandatory)
    The '+'(plus) symbol in front of a search item means that the answer MUST INCLUDE that item. This is generally used in conjunction with the permutation operation.
  • '@N' (permute)
    The '@' followed by a number indicates how many intersections to locate of the terms in your query. This may be confusing at first, but it is very powerful.

• Natural Language Query:
  You may enter a query in the form of a sentence or question. The software will automatically identify the important words and phrases within your query and remove the "noise words".

  Example:

  What is the state of the art in text retrieval?

  The software will search for:

  state of the art AND text AND retrieval

• Invoking Thesaurus Expansion
  Metamorph and Texis have an editable vocabulary of over 250,000 word and phrase associations. Each entry is generally classifiable by either its meaning or part of speech.

  To expand the meaning of a word or phrase within your query, precede it with a '~' (tilde) character.

To expand the meaning of a word or phrase within your query, precede it with a '~' (tilde) character.

• Exact: (default) Only exact matches will be allowed.
• Plural & possessives: Plural and possessive forms will be found. (s, es, 's)
• Any word forms: As many word forms as can be derived will be located.

We call this morpheme processing, and it is generally smarter than a traditional "stemming" algorithm. It doesn't just rip the end off a word, it actually checks to see if it could be a valid form of the search term.

Notes: Thesaurus terms are also treated in the same manner. Words smaller than 4-5 characters will not be processed.

• line: match terms must be located within the same line.
• sentence: all terms within the same sentence.
• paragraph: match terms must be located within the same paragraph
• page: (default) all terms within the same document.

The input form at the top allows you further tailor your query to home-in on the desired answers, or to submit a completely new query without having to navigate back to the original input form.

Each answer in the result set will have a format similar to the following:

1:

THE DOCUMENT TITLE (hyperlink to original) This is the document abstract. It consists of the first few hundred characters of text of the matching document. It is followed by the size of the document in parenthesis... http://www.rshweb.com/search.html

84% Size: 11K Depth: 3 Find Similar Match Info Show Parents

The components of each result are:

• Result number
• Document title ( clicking on this will take you to the original document )
• Abstract (The first few hundred characters of the document )
• Match quality graph. 84%( Only shown if relevancy ranking was used )
• Size ( How big is the original document )
• Depth ( How many clicks from the top of the site )
• Find Similar ( Find other documents similar to this one )
• Match Info ( View the matches and other information about the document )
• Show Parents ( List pages that link to this one )

Clicking on any match term will take you to the next matching term. A summary at the top of the in-context view shows information about the document including the time it was last modified.

Result documents are ordered from best to worst match. The bar graph display will indicate the overall quality of the match.

Note: The document you click on may not be ranked as the best match. This is because other documents may contain more information about the overall subject matter than the original.

Showing document parents - Top -  Often times it is difficult to navigate using a search engine because there is no back-link present on the matching document. The Show Parents link solves this.

This link will show other documents that contain hyperlinks to the one you click on. In other words, it is an automated back button.
