Search text in Microsoft OneNote sections Leave feedback

To search a keyword in Microsoft OneNote sections search(String) method is used. This method returns the collection of SearchResult objects. For details, see Search Text.

Here are the steps to search a keyword in Microsoft OneNote section:

• Instantiate Parser object for the initial section;
• Call search(String) method and obtain the collection of SearchResult objects;
• Iterate through the collection and get the position and text.

Warning

search(String) method returns null value if search isn’t supported for the section. For example, text extraction isn’t supported for Zip archive. Therefore, for Zip archive search(String) method returns null. For empty Microsoft OneNote section search(String) method returns an empty collection.

The following example shows how to find a keyword in Microsoft OneNote section:

// Create an instance of Parser class
try (Parser parser = new Parser(Constants.SampleOne)) {
    // Search a keyword:
    Iterable<SearchResult> sr = parser.search("Age");
    // Iterate over search results
    for (SearchResult s : sr) {
        // Print an index and found text:
        System.out.println(String.format("At %d: %s", s.getPosition(), s.getText()));
    }
}

search(String, SearchOptions) method is used for the advanced search in Microsoft OneNote sections - like search with regular expressions, search by pages etc.  SearchOptions parameter is used to customize a search.

Here are the steps to search with a regular expression in Microsoft OneNote section:

• Instantiate Parser object for the initial section;
• Instantiate  SearchOptions object with the parameters for the search;
• Call search(String, SearchOptions) method and obtain the collection of SearchResult objects;
• Iterate through the collection and get the position and text.

The following example shows how to search with a regular expression in Microsoft OneNote section:

// Create an instance of Parser class
try (Parser parser = new Parser(Constants.SampleOne)) {
    // Search with a regular expression with case matching
    Iterable<SearchResult> sr = parser.search("[0-9]{2}", new SearchOptions(true, false, true));
    // Iterate over search results
    for (SearchResult s : sr) {
        // Print an index and found text:
        System.out.println(String.format("At %d: %s", s.getPosition(), s.getText()));
    }
}
