Digital Goods Shop.The ability to search a table for data is core to the concept of DataTables, as it allows data to be easily accessed by users. This method provides the ability to control the global search of a table through the API. The global search is performed across all searchable columns see columns. If data is found matching in any column, then the whole row is matched and shown in the result set.

Searching on individual columns can be performed using the columns. DataTables has a built in search algorithm referred to as "smart" searching and is designed to make searching the table data, easy to use for the end user. A smart search in DataTables provides the following abilities:. The smart search ability of DataTables is performed using a regular expression and can be enabled or disabled using the third parameter of this method. If you wish to use a custom regular expression, for example to perform whole word exact matching, you would need to enable the regular expression option second parameter and disable the smart search option third parameter to ensure that the two do not conflict.

Note that this search ability in DataTables is actually technically a filter since it is subtractive. However, we term is a search to avoid naming conflict with the filter helper method. Please be aware that this method sets the search to apply to the table only - it does not actually perform the search.

In order to have the search performed and the result shown, use the draw method, which can be called simply as a chained method of the search method's returned object - for example table.

If there is more than one table in the API's context, the search term of the first table will be returned. Use table if you require the search term of a different table in the API's context. Set the global search to use on the table. Note this doesn't actually perform the search, but rather queues it up - use draw to perform the search and display the result.

I also tried the columns. How can I enable the individual column search, but disable the same column from the overall search?

An array of primary key values to find. The type of the array is Object. A DataRow object that contains the primary key values specified; otherwise a null value if the primary key value does not exist in the DataRowCollection.

The following example uses the values of an array to find a specific row in a collection of DataRow objects. The method assumes that a DataTable exists with three primary key columns. After creating an array of the values, the code uses the Find method with the array to get the particular object that you want. To use the Find method, the DataTable object to which the DataRowCollection object belongs must have at least one column designated as a primary key column.

When two or more rows have the same primary key value, then the first row found is returned. This occurs when EnforceConstraints is set to false.
