How does British Online Archives implement full-text search?
When you perform a search, your query is applied across all four levels of a given resource: collection, volume, document and page. Once your search request has been performed, a relevance score calculates against each collection or document. This will determine the most relevant match for the query.
Are there structured search options?
Yes. On the search results page, on the left-hand side you will find a list of filters that can be applied to refine your search. These range from particular keyword subjects and countries to specific collection titles.
Is there an advanced search feature?
Yes. The advanced search page can be found here. For help on using advanced search, please refer to our advanced search guide and video walkthrough.
Do you support operators when full-text searching?
Yes. We support various operators to help you refine and tailor your search to find the content you are looking for. A short-hand list of available operators can be found here.
Can I perform a ‘wildcard’ search?
Yes. To perform a wildcard search, you simply need to an asterisk (*) directly after a stemmed word. For example, mis* would match ‘mission’, ‘missile’, ‘miscellaneous’ etc.
How so I perform an exact search?
Also known as phrase matching, an exact search can be produced by wrapping a search query in speech/double quotation marks, for example “international conflict”. Exact phrase matching does exactly that. We do not match any other search terms even if they are related.
