Keyword Search Our search engine uses any or all keywords typed in the text box to give you product search results. For instance, typing in kvm will give you a broader set of results than kvm switch cables.
Note, however, that keywords in quotes are treated as a single phrase and will not be evaluated individually.
Booleans (AND, +, OR, NOT, -) are not supported.
Also, some keywords will not return results, and may automatically correct to a similar keyword.
Part Number Search Selection Select this Search in the drop down box to search by part number instead of keywords.
Wild Card Search The * character is only supported in a limited capacity. Using whole words is the best approach whenever possible.
"New Search" Radio Button Search the entire section that you are currently in.
"Search Within Results" Radio Button Enter keywords or a part number to limit your results within the previously searched results.
A list of all matching product categories or resources will appear in the upper left corner of the results page, when applicable, to help you further narrow your results, if you desire.
Use the "sort by" drop-down menu on the results page to sort by "most popular" and price (low to high or high to low)in the store section.
