If you search for 'The Open University' using the standard (non-API) search (https://beta.companieshouse.gov.uk/search?q=the+open+university) it is returned as the first item.
THE OPEN UNIVERSITY
Total number of appointments 1
PO BOX 77, Milton Keynes, Buckinghamshire, MK7 6BT
If you use the API search (https://developer.companieshouse.gov.uk/api/docs/search/companies/companysearch.html#here) it isn't returned at all in the first 100 records.
If the search string is 'Open University' then the API does return the correct record, as item 13.
Although this is one example I am sure that there will be others.
Can the API Search be brought into line, our users would expect this search to work.
