Search Tips
This document introduces basic search concepts, and describes advanced techniques that produce more efficient search results.

Getting Started with Search

To search for a document, type a few descriptive words in the search box, and press the Enter key or click the search button. A results page appears with a list of documents and web pages that are related to your search terms, with the most relevant search results appearing at the top of the page. By default, only pages that include all of your search terms are returned. So to broaden or restrict the search, include fewer or more terms. For example, to search for engineering product specification documents, type the following:

engineering product specifications

The search appliance uses sophisticated text-matching techniques to find pages that are both important and relevant to your search. For instance, the search appliance analyzes not only the candidate page, but also the pages that link to it, too. The search appliance also prefers pages in which your query terms are near each other. Every search result lists one or more snippets, or excerpts from the document, to display the search terms in context. In the snippet, your search terms are displayed in bold text so that you can quickly determine if that result is from a page or document you want to visit.

Note: Encrypted, viewable PDF documents are converted to HTML for indexing, but the HTML is not displayed.

Capitalization

The search appliance searches are not case sensitive. All letters, regardless of how you enter them, are handled as lower case. For example, searches for "george washington", "George Washington" and "George washington" return the same results.

Date Sort

By default, search results are sorted by relevance, with the most relevant result appearing at the top of the page. If you want to sort the documents by date instead, click the Sort by Date link. The most recent document appears at the top of the page and the date of each file is returned in the results. Results that do not contain dates are displayed at the end and are sorted by relevance.

Widening Your Search

You can expand your search by using the OR operator. To retrieve pages that include either word A or word B, use an uppercase OR between terms. For example, to search for an office in either London or Paris, type the following: "office london OR paris"

Refining Your Search

Since the search appliance returns only web pages that contain all of the words in your query, refining or narrowing your search is as simple as adding more words to the search terms you have already entered. The refined query returns a subset of the pages that were returned by your original broad query. If that does not get the results that you want, you can try to exclude words, search for exact phrases, or restrict the search to a range of numbers. These techniques are described in the following subsections.

Word Exclusion

If your search term has more than one meaning, you can focus your search by adding "NOT" in front of words related to the meaning you want to avoid.

For example, to search for the planet Saturn and exclude search results about the car company or Roman god, type the following query: "Saturn NOT car NOT god"

The search appliance returns pages about Saturn that do not contain the word "car" or "god."

Phrase Searches

Phrase searches are useful when you are searching for famous sayings or specific names. You can search for an exact phrase or name by enclosing the phrase in quotation marks. The search appliance only returns documents that include the exact phrase you entered.

Quotation marks join your search words as a single unit. For example, if you type the following query, the search appliance treats it as a phrase search even though the search words are not enclosed in quotation marks.
