No, there´s no such feature in InDesign. Actually the text InDesign exports, if use SWF as a format, is quite a mess. Words are splitted to separate characters and it´s not even closely in searchable form.
3rd party finalizing tool for SWF files exported from InDesign - eDocker - can however create a simple keyword search for you document. Search is still in beta feature but it works if you just need to have a textfield where end-user can write a word or phrase to search for. After clicking search button, he/she will receive a list of search results, which are also links pointing to those pages where actual results are.
Check for instance this link:
Try word empire and you will get few results to pages where that word can be found.....
You will find eDocker here>>
Thank you very much for your feedback!
I thought since in the swf export options you could choose Flash Classic Text to output searchable text that there may be a way to add that feature to the document. I am going to look into the options you suggested, but off the top of your head do you know if eDocker allows the interactivity features a swf file that a pdf doesn't (ie. animation)?
Yes, eDocker supports all the interactivity that InDesign can create to SWF files; animations, multistate objects, hyperlinks, buttons, videos.
Check this interactive sample:
-slideshow made with multistate objects at page 2
-video and hyperlinks at page 3
-animation that user have to trigger at page 4 (touch the edge of image on top-left corner)
-animation that starts on page load at page 4-5
