Search Tips


The Basic Search

To enter a query, type in a few descriptive words and press the Enter key or click the Search button for a list of relevant results.

QNX uses sophisticated text-matching techniques to find pages that are both important and relevant to your search. For instance, QNX analyzes not only the candidate page, but also the pages linking into it to determine the value of the candidate page for your search. QNX also prefers pages in which your query terms are near each other.

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

Automatic "and" Queries

By default, QNX only returns pages that include all of your search terms. There is no need to include "and" between terms. For example, to search for engineering product specification documents, enter:

To broaden or restrict the search, include fewer or more terms.

"OR" Searches

QNX supports the logical "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, enter:

See Your Search Terms in the Results

Every QNX search result lists one or more excerpts from the web page to display how your search terms are used in context on that page. In the excerpt, your search terms are displayed in bold text so that you can quickly determine if that result is from a page you want to visit.

Does Capitalization Matter?

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

Does QNX Use Stemming?

To provide the most accurate results, QNX does not use "stemming" or support "wildcard" searches. Rather, QNX searches for exactly the words that you enter into the search box.

For example, searching for "airlin" or "airlin*" will not yield "airline" or "airlines.". If in doubt, try both forms, for example: "airline" and "airlines."

Refining Your Search

Since QNX only returns 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 specific subset of the pages that were returned by your original broad query.

Excluding Words

You can exclude a word from your search by putting a minus sign ("-") immediately in front of the term you want to exclude. Make sure you include a space before the minus sign.

For example, the search:

will return pages about bass that do not contain the word "music."

Phrase Searches

You can search for phrases by adding quotation marks. Words enclosed in double quotes ("like this") appear together in all returned documents. Phrase searches using quotation marks are useful when searching for famous sayings or specific names.

Certain characters serve as phrase connectors. Phrase connectors work like quotes because they join your search words in the same way double quotes join your search words. For example, the search:

is treated as a phrase search even though the search words are not enclosed in double quotes. QNX recognizes hyphens, slashes, periods, equal signs, and apostrophes as phrase connectors.
