MIMOSA User Guide- page 21 If, for example, a database has an NP criterion containing the value "US168,034", the only query which will normally retrieve this document is NP = "US168,034". If you enter the query NP = "US168 034" or the query NP = "US168/034", without filters MIMOSA would not retrieve the document. Three types of criteria have filters : classification, date and number. For these criteria MIMOSA applies a pre-processing operation which transforms the terms searched for such that their format corresponds exactly to that in the database. For example, by applying an appropriate filter, MIMOSA will transform the query PD=30/11/1989 into PD="19891130" before it searches through the database. Criteria with filters are proceeded in the criteria list with a specific icon for each type : Filter Associated Icon Date Number Classification 4.1.9. Date filters If a separator character (either . or – or , or /) is detected in a search query on a date criterion, MIMOSA transforms the date into the format used in the database. If none of these characters are detected, the date must be entered in exactly the format used in the field index. MIMOSA recognizes the following date formats: Format DD/MM/YYYY DD/MM/YYYY DD.MM.YYYY DD-MM-YYYY Example 01/12/1997 01.02.1997 01-12-1997 Format YYYY/MM/DD YYYY/MM/DD YYYY.MM.DD YYYY-MM-DD Example 1997/12/01 1997.02.01 1997-12-01 Note, if MIMOSA detects a wildcard in the term searched for ( *, ? or # ), no processing is carried out. For example, the query AD=1996/12/0* does not return any document. There follows a list of date filter examples. Zero results imply improper use of the date filter.
