WebViewer({ … }, viewerElement).then(instance => {
const { annotManager, docViewer, Annotations } = instance;

const searchListener = (searchPattern, options, results) => {
// add redaction annotation for each search result
const newAnnotations = results.map(result => {
const annotation = new Annotations.RedactionAnnotation();
annotation.PageNumber = result.pageNum;
annotation.Quads = result.quads.map(quad => quad.getPoints());
annotation.StrokeColor = new Annotations.Color(136, 39, 31);
return annotation;
});

annotManager.addAnnotations(newAnnotations);
annotManager.drawAnnotationsFromList(newAnnotations);

};

docViewer.on(‘documentLoaded’, () => {
const searchPattern = ‘text to search’;
// searchPattern can be something like “search*m” with “wildcard” option set to true
// searchPattern can be something like “search1|search2” with “regex” option set to true

// options default values are false
const searchOptions = {
  caseSensitive: true,  // match case
  wholeWord: true,      // match whole words only
  wildcard: false,      // allow using '*' as a wildcard value
  regex: false,         // string is treated as a regular expression
  searchUp: false,      // search from the end of the document upwards
  ambientString: true,  // return ambient string as part of the result
};

instance.addSearchListener(searchListener);
// start search after document loads
instance.searchTextFull(searchPattern, searchOptions);

});
});

Hello there.

Thanks for reaching out.

This is the expected behavior. The search is only actually triggered when the search button is clicked, then it will take the search input value and use it as the input.

Let me know if you have any further questions.

Hi,

After clicking the search button also, it is showing the previous search result.

Hello there.

I really can’t reproduce this issue on WebViewer 7.3. Would upgrade your WebViewer version to 7.3 be possible? Maybe this was an issue that is already solved.
