Missing search results in the Test App

[mickael-menu]

Hi, you can reproduce the problem with the TestApp (app version 2.6.1), with the ePub: "Voyage au centre de la terre" (OPDS 2.0 Test Catalog) searching the keyword 'science'.

Making a text search inside an ePub, sometimets I got only one result, but there are many.

Moreover during the digitation it will show some correct result that contain entirely the searching word, but for any pressed key, they will be hidden or shown without any apparent logic.

Finally, if I tap on the result, I'll go to the correct page and here if I repeat the search I'll got all the results.

This seems to be an UX issue in the Test App, the search API in the toolkit is working correctly.
