About search options

This topic explains single or multiple word searches, but not searches by patterns or masks (custom patterns).

You can refine your search with basic and advanced options.

Basic search options

Basic search options appear at the bottom of the Search floating window.

  • Match whole word only: Select this check box if the search text you specify must be a self-standing word. For instance, if you are looking for the word "is" but want to filter out words such as "list", "mistake", or "rediscovered" (all containing the letter combination "i+s"), selecting this check box only finds the correct results.

  • Match case: Use this setting if capitalization is important. If you select only this check box, but not "Match whole word only", the search returns the correctly capitalized words. For example, if you specify "Apr" as the Search Phrase, the search finds all occurrences of the word "April", but none for the word "apron".

    Suppose you have a PDF with one occurrence of the word "Tropical" capitalized. If you select Match whole word only but leave Match case unselected, the Search Phrases "Tropical", "tropical", or any miscapitalized versions of the same word such as "TROPICAL" or "tRopical" return the correct result. However, word segments (even if capitalized correctly, such as "Trop") do not return any search results.

    If you select both check boxes, only the Search Phrase "Tropical" returns the correct result. Use this setting if you are interested in only the given word (and not in any of its affixed variants) and you are sure that there are no misspelled occurrences of it.

  • Include Comments: Select this check box to search comments as well as the text content of your PDF.

  • Include Bookmarks: Select this check box to search bookmarks as well as the text content of your PDF.

Advanced search options

You can narrow the search, using document properties (author, title, subject, keywords) when performing a folder search for single or multiple words.

Click Advanced and define values for the properties in the Additional Criteria list near the bottom of the Search dialog box.

Narrowing the search means that the program searches only for the given phrase and only in documents that meet the given criteria. The list has the following buttons and headers.

  • New Criteria: Click this link to add a new empty item to the list. Specify a criteria for searching by providing Key, Operation and Value in the new item.

  • Key: Select from Author, Title, Subject, Keywords, Application, Producer, Created Date, or Modified Date in the drop-down list.

    Select <Delete> to remove the item from the criteria list.

  • Operation: For a date-type key, you can select any of the following: Is Before, Equal To, Not Equal To, or Is After. For all other keys, you can select between Includes and Excludes.

  • Value: Type in or select a value.

    For most key types (not for dates), you can specify several values to be included or excluded.
