问题
Using phpGrid, I have created a single grid with a number of customizations, including a global search similar to Oleg's example here: Universal search field for jqgrid
Now, I am attempting to implement multi-word search (e.g. JQGrid Toolbar Searching: search for multiple words for a column) with the global search, but haven't been able to get it working. Submitting multiple words (i.e. tricolor rat terrier) should search all of these words. Submitting multiple words in quotes (i.e. "rat terrier") should search the exact term.
Note that I have not yet implemented highlighted search terms, however I do plan to.
Code snippet:
// Add global search
$("#data_toppager_center table tbody tr").append($("<td><div class=\"fieldcontainer\"><input type=\"text\" name=\"gs\" id=\"gs\" class=\"searchfield\" placeholder=\"Keywords...\" tabindex=\"1\"><input type=\"submit\" name=\"gsbtn\" id=\"gsbtn\" value=\"\"></div></td>"));
var $grid = $("#data");
$("#gs").keypress(function (e) {
var key = e.charCode || e.keyCode || 0;
if (key === $.ui.keyCode.ENTER) { // 13
$("#gsbtn").click();
}
});
$("#gsbtn").button({
text: false
}).click(function () {
var postData = $grid.jqGrid("getGridParam", "postData"),
colModel = $grid.jqGrid("getGridParam", "colModel"),
rules = [],
searchText = $("#gs").val(),
l = colModel.length,
i,
cm;
for (i = 0; i < l; i++) {
cm = colModel[i];
if (cm.search !== false && (cm.stype === undefined || cm.stype === "text")) {
rules.push({
field: cm.name,
op: "cn",
data: searchText
});
}
}
postData.filters = JSON.stringify({
groupOp: "OR",
rules: rules
});
$grid.jqGrid("setGridParam", { search: true });
$grid.trigger("reloadGrid", [{page: 1, current: true}]);
return false;
});

I think that one can relatively easy combine two solutions which I suggested before. The resulting demo allows to make global search (search in any searchable column) for multi-word text (multiple values divided by space separator):

The full code which I used in the demo is below:

"use strict";

UPDATED: To allow to use quoted strings with spaces in the global searching string you can use match instead of split. The modified demo allows to use the following
