| Operator | Example | Action | Boolean Equivalent |
|---|---|---|---|
| " " | "temperature monitoring" | Requires two terms to be adjacent to each other. In this example, only documents containing the phrase "temperature monitoring" will be shown. | ADJ |
| + | +temperature | Requires this term to be present as-is, eliminating the use of synonyms. This search query can be used in conjunction with other keywords to find only documents containing the word "temperature". | AND |
| - | -monitoring | Excludes results containing this term. Use this query in conjunction with other terms to find only documents not containing the word "monitoring" | NOT |
| () | (temperature monitoring) | Allows terms to be grouped when used with other operators. For example, searing for industrial -(temperature monitoring) will return only documents containing "industrial" but not "temperature" or "monitoring" | OR |
| * | monitor* | Acts as a wildcard. This example will return documents containing words "monitor", "monitoring", "monitored", etc | n/a |
