Quick Search, Advanced Search and Search within results.
Please type in your desired keyword (one or multiple words or phrases) in the text box. The search will be performed in the following ways:
- If keywords are separated by space or commas, your results will contain either of those words, as well as both (OR search).
For example, if your input is programmable logic, you will get results containing programmable or logic or both.
- If you use "+" to connect words, you will get only results containing all the keywords (AND search)
For example, if your input is +programmable+logic (note that there is no space between + and the word), only articles containing both programmable and logic will be generated.
- If you enclose keywords within quotation marks, the search engine will pull up articles containing exact matches.
For example, if you input "programmable logic", only articles containing programmable logic (in the same order that you have input the words) will show up.
To narrow the number of results, you may use Advanced Search. On the Advanced Search page, input your keywords separated by space or comma. Then choose any of the three options: Match All Words, Match Any Word or Exact Search.
- Match ALL words (AND):
If you select this option, the search results will contain all the keywords you input.
- Match ANY words (OR):
If you select this option, search results will contain any and all of the keywords you input.
- Exact search:
In this case, only articles containing exactly the same keywords will be included in the results.
