See if a word exists in any segment, or is an exact segment match.

If URL is mysite.com/giving-birth-here/your-team/nurses-staff/, then the following if statement will return true.

{if "{exp:in_segments value='staff'}"}
    {embed="global/_staff_list" category="4"}
{if:else}
    {embed="global/_staff_list" category="5"}
{/if}


Parameters
------------------
value= (required) the string of text you're searching for. Can be a pipe delimiated list that will search for multiple words in segemnt. If any of the words are found, it will return true.

exact= (optional) set to'y' to do an exact segment match. In the example above only 'nurses-staff' would return as true.

return_segment= (optional) set to 'y' to return the segment number in which the match was found. By default the plugin returns true/1 or false/0.
