That should give you what you want. It's looking for exact text matches (not case sensitive).
For each keyword, the comma serves the function of “OR.”
If you have added more than one search term, your search rule looks to find at least one of the listed terms.
You could look to add inclusions to a keywords rule:
This helps you to narrow down your search so you get a much higher quality selection of posts and results. Think of inclusions as the word “AND.” Your search will be filtered so that posts are selected only if they contain at least one of the keywords AND at least one of the inclusions. Inclusions aren’t case-sensitive.
(When you set up your search rule, you can choose from the following options to decide how close a keyword and an inclusion must appear in a post:
* Sentence: Keywords and inclusions must appear in the same sentence.
* Paragraph: Keywords and inclusions must appear in the same paragraph.
* Post: Keywords and inclusions must appear in the same post.)
Microsoft recommend starting with the default option (paragraph). If your search topic yields too many irrelevant results, try narrowing it to the proximity in a sentence. Note that this may also remove relevant posts because all combinations of inclusions and keywords outside of a sentence will no longer be picked up by the keywords rule.
Note:
Although you can create an unlimited number of search queries per search topic, there is a limit on the length and number of terms.
Maximum length, in characters, of search topic names: 35.
Maximum length, in characters, per keyword, inclusion, and exclusion: 128.
Maximum number of keywords per search rule: 15.
Maximum number of inclusions per search rule: 15.
Maximum number of exclusions per search rule: 25.
