On this tab, you can modify the general properties of the currently edited search index. It is the same properties that you define when creating a new search index:
|•||Display name: name of the index displayed in the administration interface|
|•||Code name: name of the index used in website code (the fully qualified file name must be less than 260 characters long, the directory name must be less than 241 characters long)|
|•||Analyzer type: type of analyzer that will be used when indexing the content of your site, the following types are available:|
|•||Standard - grammar-based analyzer (stop-words, shortcuts, ...), very efficient for English, but may not produce satisfactory results with other languages|
|•||Simple - divides text at non-letter characters|
|•||Stop - contains a collection of stop-words at which it divides the text|
|•||White space - divides text at whitespaces|
|•||Keyword - tokenizes the entire stream as a single token; this is useful for data like zip codes, ids, and some product names|
|•||Stop words - dictionary containing words which will be omitted from indexing (e.g. 'and', 'or', ...) when a Stop or Standard analyzer is used; the dictionaries are stored in ~\App_Data\CMSModules\SmartSearch\_StopWords|
|•||Index type: type of content to be indexed|
|•||Documents - indexes content of documents in the content tree|
|•||Forums - indexes content of discussion forums|
|•||Users - indexes details about system users - fields of the CMS_User system table|
|•||Custom tables - indexes records in custom tables|
Besides modifying these properties, you can Rebuild the index, which deletes the original one and the specified content gets indexed again. Clicking this action button does not always guarantee that the index will be rebuilt immediately. The process may be delayed if e.g. another index is already being rebuilt or if the rebuilding tasks are configured to be handled by the scheduler. The index is automatically optimized after a successful rebuild.
You can also Optimize the index, which results in better search performance, particularly in case of large indexes.
In the Index info box, you can find some self-explaining information about the index.
