So you want an AND search using each of the words entered, rather than the exact string? Howabout something like this:
var yourSearchText = 'World Hello';
var searchTerms = yourSearchText.split(' ');
var searchTermBits = [];
for(var i=0; i<searchTerms.length;i++) {
searchTermBits.push("word LIKE %"+searchTerms[i]+"%");
}
var result = searchTermBits.join(" AND ");
var query = 'SELECT * FROM TABLE WHERE '+result;
this will give you a query like:
SELECT * FROM table WHERE word LIKE '%world%' AND word LIKE '%hello%'
change the AND to an OR if you want to match any of the search terms rather than all.
