For an example string of "searching", you can query the MDB database to get all the forms that include it, along with the relevant fields.
select b.form_entity_name as form, e.form_entity_name as field, a.attr_value as value
from usm_form_component_attributes a, usm_form_entities e, usm_form_entities b
where e.form_entity_id = a.form_comp_id
and b.form_entity_id = e.form_entity_parent_id
and a.attr_value like '%searching%'
and b.form_entity_type = 2
