The fastest way to get started is to instantiate FSDataSource, passing a File or
|
|
Directory into the constructor. Then in SearchIndexer, invoke indexDataSource and
|
|
pass in the FSDataSource in as a parameter. The other argument of indexDataSource,
|
|
customFields, is for declaring what are the types of the fields you wish indexed.
|
|
It's an optional argument.
|
|
|
|
Now you might want to try writing your own DataSource by writing a class which
|
|
implements the DataSource interface. The only method you need to implement in the
|
|
DataSource interface is the getData method which returns an array of Maps.
|
|
From the javadoc of this method, "Each map represents a document to be indexed.
|
|
The key:value pairs of the map is the metadata of the document.".
|
|
That should be pretty self-explanatory. What the framework essentially does is
|
|
convert all keys in the map as Fields, and the value of the keys becoming the
|
|
value of the Fields. It's that simple! |
