To carry out a search on solution, the "Search on solution" box must be checked. The field used to enter the significant words is then accessible. Each search can take into account several keywords. Each of them must be separated by a space.
It is possible to recover any keywords entered in a search on the title and description. If the user checks the "Identical keywords" box, all the words entered in the text associated with the search on the title and description are recovered in this text field.
