About building/rebuilding Exalead indexes
To build/rebuild all Exalead indexes, in the folder where srv4.exe resides (typically C:\TERA\GN4\BIN), create in the Notepad an empty text file with the name all.xml and paste into it the below xml code:
<SearchConditions
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.teradp.com/schemas/GN4/1/SearchConditions.xsd"
ObjectTypeName="folderObject"
/>
Then, in the Command prompt window, execute the command:
srv4 index -conditions all.xml

Note
Once the TARK4/GN4 schema and Exalead are configured, it is possible to index existing objects. Moreover, you need to rebuild Exalead indexes if you created GN4 database, if you restored a database dump from another GN4 server, or if you changed the indexing structure.
Troubleshooting
If the reindexing by means of srv4 with conditions gn4:folderObject doesn't seem to finish after unexpectedly long period of time, it may be that the job analysis is stuck. To resolve it, stop Back4 service, remove all the reindexing from the database, remove the Exalead indexes and restart the server. Reindex one-by-one various object classes (images, videos, stories etc).
