Inconsistent results using EE Simple Search with Solspace Calendar

Question

I am using EE's Simple Search here to search the Solspace default channel Calendar:Events.

Here is the code

<div class="calendar-search">
    <h3>Search Events</h3>
    {exp:search:simple_form 
        channel="calendar_events" 
        search_in="everywhere" 
        where="any"
        show_future_entries="yes" 
        show_expired="yes"
        results="10" 
        result_page="calendar/search-results" 
        no_result_page="search/no-results"
        }
    <input type="text" name="keywords" id="keywords" value="" size="18" maxlength="100"> <input type="submit" value="Submit" class="search-btn">
{/exp:search:simple_form}
</div>

For most search items this works fine and delivers predictable results. However, there are a couple of things that don't work and I haven't been able to find solutions to the following:

1. No results for items I know are in the entries. For example, there is an event with the title of Lego Club, but if I do a search for Lego, I get a blank results page.

2. The No Results page is not being used for items that are not in the channel. For example, if I do a search for Nikon, instead of going to the designated no_result_page it goes to a default EE page that displays the following error:

The action you have requested is invalid.

I am not sure why these errors are occurring or how to fix them, but would appreciate any insights.

Answer 1

Sounds like your #2 is related to EE's "Secure Mode" with form submissions. You can read more about it here: https://ellislab.com/blog/entry/putting-the-secure-in-secure-mode-forms

Try adding this line of code immediately above your "keywords" input field.

<input type="hidden" name="XID" value="{XID_HASH}">

This may also fix your #1 issue but I can't say for sure. I'd imagine that without the {XID_HASH} code in place, none of your searches would work but since lots are working I'm a little perplexed. Give this a try.
