When using a keyword search, the strategy is very different from using a Google Search because the search engine doesn't give a best guess.
- Word length: Words with only two letter words are ignored unless specifically whitelists, such as US
- Commas and Semi-colon , ; : These are used to separate words and phrases for indexing. They are therefore ignored in a search.
- Full Stops: Full stops after words are ignored but those within a text string are not. Therefore avoid full stops within words or acronyms. So avoid "U.S." and use "US" instead. "US." If in doubt put word or phrase in apostrophies.
- Slash / : These are ignored in a search so 2019/20 will search for 2019 - the 20 being ignored as it is two characters . Ditto 9/11 will search for 9 11 and as these strings both have fewer than two characters there will be no hits
- Dash - : If a dash is included anywhere in a search it will be "read" as a space. 2020-21 will therefore be ready as 2020 21. The 21 will be ignored (as all two letter words are ignored unless whitelisted). So 2020-21 will search fo 2020. .
