Yes, I think it should not search in the image-tag content.
for example, all images are stored in the directory "
http://ludothekprogramm.ch/images/forum/". when the user searches for "images" it brings all items with included a image. this makes not really sense.
further, it skips the image tag from search result excerpt, which results in short an bad text in the search result (see attached image in my question: "
...träge FallallSpiel vor...." is no german word neither sentence, its a wrong string, resulting from stripping img-tag out in some way...
