This option allows you to specify that your terms must appear adjacent to one another and in the exact order in which they were entered. This is helpful when looking for names of people or organizations. Proximity Some databases allow you to use proximity searching to insist that the search terms appear close to one another within the document. Wildcard This technique is similar to truncation in that it allows the insertion of a character to retrieve variant forms of that word. The difference is that the wildcard character may be inserted within the word.
Databases vary in how they treat the techniques outlined above.
