Each record usually corresponded to one paragraph. Documents stored in an infobase were usually made up of more than one record. In contrast, LivePublish uses a document model. Each document stored in an infobase corresponds to one source document. LivePublish serves one document at a time, exactly as it was stored in the infobase.
Searches return documents containing matches for the search criteria.
Because a LivePublish document collection file is document based, you need to divide the 4.x infobase into portions, which represent about a page of information. When running the Migration Tool you may specify the level at which the infobase should be split into documents. You should break your infobase at levels a web browser can display at a reasonable performance level. In addition to the default split level, you can configure the Migration Tool to split an infobase on specific headings.
