Setting Index Options for Projects
Syllable and Member indexing takes up index space on disk and in memory. It also slows database access a little bit. You can control what is indexed in the Project Settings dialog box.
Two check boxes control indexing:
Quick browsing for member names
Check this to allow member name indexing. When this option is enabled, you can simply type the member names of classes or structures, instead of having the type the class or structure name, followed by a dot (.) and the member name. Un-checking this will save on disk space and memory.
Quick browsing for symbol syllables
Check this to allow syllable indexing. When this option is enabled, you can type partial syllables and find symbols containing those syllables. Un-checking this will save on disk space and memory. If your project is large, then Source Insight may operate slowly when browsing, or synchronizing files with the symbol database.
If both check boxes are turned off, then the Browse All Symbols dialog box, and the Project Window symbol list filtering will revert to simple prefix matching. However, the Symbol Window on the left side of each source window, and the Project Window file list will still allow syllable browsing.
