Difference between version 36 and version 35:

Line 41 was replaced by line 41
- In general, the {{search}} operation requires access to all semantic annotations (i.e., for remote searches all remote annotations) to find matching resources. Because of this requirement, as the number of semantic annotations increases, this operation can become expensive.
+ In general, the {{search}} operation requires access to all semantic annotations to find matching resources. For example, if a search expression requires both concepts {{A}} and {{B}}, the algorithm must look for annotations that explicitly state {{A}} and {{B}} as well as those that state only {{A}} and only {{B}} (which taken together make {{A}} and {{B}}). Thus, for remote searches, the algorithm must consider all remote annotations to find matching resources. Because of this requirement, as the number of semantic annotations increases, this operation can become expensive.
