Horizon Index Services supports other settings that are not included in the issettings.conf configuration file by default. If you want to, you can add one or more of these settings to the configuration file to override the default value that Horizon Index Services uses.
The table below shows the additional settings you can add to the configuration file. To add any of these settings, type the setting name in uppercase, followed by a space and the value you want for the setting. (For instructions on editing the configuration file, see Updating Horizon Index Services Settings .)
Setting |
Description |
INDEX CHUNK SIZE |
Enter the number of records you want the Indexer to process between index saves. 50000 is the default that the Indexer uses unless you add this entry to the configuration file and enter a different number. As the Indexer builds the index in mass mode, it saves its work periodically. This setting lets you specify how often the Indexer performs a save. If the Indexer is interrupted for any reason, only the indexing performed since the previous save is lost. If you resume the build, the Indexer will resume from the previous save, rather than rebuilding the entire index. |
INDEX PARTITION SIZE |
Enter the number of records to include in each index partition. 2 million (2000000) is the default that the Indexer uses unless you add this entry to the configuration file and enter a different number. This setting lets you control the size of your index partitions (or files) so they do not exceed the maximum size of 2GB. When the number of records for a partition reaches the number you specify here, the Indexer creates a new partition and begins saving index information to the new partition. The recommended setting of 2 million will work for most libraries since the average file size for 2 million records is 1GB. However, you may need to enter a smaller number if your bib records are generally larger than average (for example, because of locally-defined tags). |
SEARCH SERVER THREADS |
Enter the number of threads you want the Search Server to start with. The Search Server will start with 6 threads unless you add this entry and enter a different number. In general, you will want about one thread per 30 concurrent Information Portal users. |
