Drupal.settings.IAS_settings.word_size could be a string

Hello,

the contributed search box (/search/inline_ajax_search) did not work for me.
The keyup event was triggered but the HTTP request was not send.

The problem was, that "Drupal.settings.IAS_settings.word_size" was set to the string "3,3" and is compared later ("$(this).val().length >= Drupal.settings.IAS_settings.word_size").

I configured the "minimum_word_size" to be 3 at "/admin/settings/search". This seems to be the "word_size". I'm not sure if this is a local problem and I don't really know where the "3,3" occours, but I fixed it temporary by validating "Drupal.settings.IAS_settings.word_size" to be a number and setting the default value if not.

After this fix, the contributed search box worked without problems.

Thanks in advace.
