Advanced Search Options
Applying Search LogicTexis 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" .

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.
More information is available at Notes: Thesaurus terms are also treated in the same manner. Words smaller than 4-5 characters will not be morpheme processed. Controlling Proximity These options give you control over the region in which a match must be found.
In all cases the best possible matches for your query are located and ordered by decreasing quality. A bar graph is produced to indicate the quality of each answer. |
