Description copied from class: Query

Used by getSearchString to build up the query string recursively from the parts. Note that the work is done on the unwinding phase of the recursion. Those query fragments that must appear first or last in a query string defer being added to the string until the end, by putting a reference to themselves intoone of the two lists. These lists are then processed at the end after some verification.

Specified by:

buildSearchString in class Query

Parameters:

start - the list of query objects that must come first in a Google query

finish - the list of query objects that must come last in a Google query. e.g. site:

Returns:

the query string
