A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Network administration for a Multimaster Mesh

SA does not require that a Multimaster Mesh configuration meet specific guidelines on network uptime. A Multimaster Mesh configuration can function acceptably in a production environment that experiences temporary inter-facility network outages.

However, as the duration of a network outage increases, the probability of conflicts increases. Extended network outages between facilities can cause the following problems:

Multimaster messages can fail to propagate between facilities
The Multimaster Tools can stop functioning
SA Clients cannot contact the multimaster central Data Access Engine

Production experience for multimaster configurations supports the performance data that the following table shows.

**Performance data for Multimaster configurations**
Number of Facilities	Duration Network Outage	Number of Multimaster Conflicts *
8 facilities (SA core installed in each facility)	12 hour outage (1 facility loses network connectivity to the other facilities)	12 to 24 conflicts (average number generated)
* The propensity of users to manage servers in the disconnected facility with SA Clients in other facilities increases the number of conflicts.

Network connectivity issues include SA Bus or multicast routing problems.
