Improving the Relevance of Search Results
Web Search returns descriptions of each hit that is listed on the search results
page. By default, the following information is displayed:
Description field
Summary field
Abstract field
The first 255 characters of the document (beginning with first heading
and skipping links)
The first three fields are created from the content of META tags in HTML
documents. If these tags are not defined, Web Search will try to find the first
heading and begin selecting words. If it can't find a heading, then it begins at
the top of the document and selects the first 255 relevant display bytes as the
description.
Web Search utilizes a sophisticated relevance-ranking algorithm. During a
search, Web Search considers
The number of times words appear in a document
The proximity of words in a multiple word search (the closer the words
appear, the more relevant the document will be)
The order of words in a multiple word search (the exact order of words is
more relevant)
The location of words in a document (specifically words that appear in a
META tag, title, body, header, footer, etc.)
The formatting of words in a document (such as bold, font type and size,
etc.)
Query weighting in a multiple query scenario
The number of times words occur within an entire index (for example, the
word the has low relevance)
