Supported types of searches:
- Single keyword search
The search engine returns pages containing the keyword.
- Multiple keyword search
By default, the search engine only returns pages containing all of the keywords. This is the same as using the AND operation between each word.
Ex: injection volume
- Phrase search
Put a search phrase in quotes to only return pages containing the exact phrase.
Ex: "void fraction"
- Boolean search
The AND operator indicates that the keyword before and after must be present on the page.
The OR operator indicates that either the keyword before and/or the keyword after must be present on the page.
A '+' sign before a keyword indicates that it must appear on the page.
A '-' sign before a keyword indicates that any page containing the keyword should not be returned.
Ex: flow AND rate
Ex: "Van Deemter" OR "resolution"
Ex: chromatography -gas
