Search with Boolean operators
A Boolean search of PDF documents provides more search options by letting you combine search criteria in a clearly defined way (using logical operators). It applies only when multiple documents are searched; it does not apply when searching by patterns or masks. When searching for multiple search words or phrases, an OR search is performed; that is, each occurrence of either search string will be reported. This means Boolean operators are no longer needed to do OR-type searches. AND-type searches (where both strings must be present, so fewer results are generated) can only be done with Boolean operators.
To use a Boolean query in a multiple-document search:
- Select Search Multiple in the list to display the floating Search panel. , and then select
- Select the Select Index item in the Look In list.
- Select an index or more indexes in the Index Manager dialog box and click OK.
- Click Advanced and select Boolean query in the Match list.
- Type the query for the search terms, using Boolean operators and syntax. On building queries, see Advanced search options. See the description of Boolean operators in Boolean operators.
- Proceed with step 6 on as detailed in Search in multiple documents.
