Issue: only one missing word can make the search fail.
Use cases: typo in a word, use of synonym term, unsupported derived form (stemming not enough powerful)…
Requested solution: relaxing 'AND' operator to use 'OR' by default instead between query terms. This way, even if one wrongly spelled word is present, the other query words may help to find better results.
Examples:
- Je suis *venir* te dire que je m’en vais vs Je OR suis OR venir OR te OR dire OR que OR je OR m’en OR vais (T241265)
- John *Fitgerald* Kennedy vs John OR Fitgerald OR Kennedy
Anyway, according to inline doc (“There may be results that do not contain one or more of your search terms.”, relaxing 'AND' is expected.
