Disable search indexes by modifying jar

[Mr.Samuel]

With many trial and errors, I finally find a way to disable search indexing on any conditions.

First, dump the /opt/amazon/ebook/lib/kafindexer.jar file in your kindle's rootfs with the KUAL extension named kindle explorer or usbnetwork for modification.
Then modify the "allowedToStartIndexing" method of \com\amazon\kindle\indexer\bundle\IndexerThread.cl ass file in the dumped /opt/amazon/ebook/lib/kafindexer.jar file like this to disable the indexing thread.

I modified it with JBE.
After that, compress the class file to the jar file and push the jar file into the corresponding place of your kindle's rootfs.

Now I post the already-modified file for fw 5.8.7

[Mr.Samuel]

And I still have a question:
How to modify the functions of "Quick Action" menu?
I want to modify the second button as "Browser", but after I make change to the javascripts in webkit-1.0 folder, it does not make any changes.

Isn't it in the webkit folder?

[Mr.Samuel]

The way of disabling search indexing is helpful for kindlers who thinks the search index function is not very useful and want to save the space and battery of kindle.
