33 ;"=======================================================================
34 ;"Search string examples:
35 ;" 8925:.02(.01="SMITH,JOHN")
36 ;" 1234:.01(.03in"32..55") <-- this is a range test
37 ;" 1234:.99((.01="SMITH,JOHN") OR (.01="SMITH,BILL")) AND 4567:.01(.02'="4/2/10") NOT (1["HAPPY")
38 ;" 8925:(REPORT TEXT[DM-2)!(REPORT TEXT[HTN) AND 120.5:((VITAL TYPE=PULSE)&(RATE>70)) Targetfile=2
39 ;"
40 ;"SYNTAX:
41 ;" -- File specifier. To specify searching in a file OTHER THAN target filenumber, an optional
42 ;" FILENUM:FLD[:FLD[:FLD...]] may be specified. However, ultimately, this must point back
43 ;" to the target filenumber. E.g. Search in file 8925, but for each entry found, use the IEN
44 ;" specified by FLD (or FLDA:FLDB or FLDA:FLDB:FLDC:...). NOTE: If just FILENUM is provided
45 ;" without specifying FLD(s) to point to target filenumber, then the code will find a path
46 ;" (if possible), using first one found.
47 ;" FILENUM:(...)
48 ;" The logic is read from left to right, honoring parentheses. If a filenumber
49 ;" is not specified, then the last specified filenumber is used.
50 ;" E.g. 1234:.01( LogicA ) OR 234:.99( LogicB ) AND ( LogicC )
51 ;" LogicA fields refer to file 1234:.01.
52 ;" LogicB fields refer to file 234:.99
53 ;" LogicA fields refer to file 234:.99 (last specified file number)
54 ;" E.g. 5678:.01( (LogicA1) OR 5432:.88(LogicA2) NOT (LogicA3) ) or (LogicB)
55 ;" LogicA1 fields refer to file 5678:.01
56 ;" LogicA2 fields refer to file 5432:.88
57 ;" LogicA3 fields refer to file 5432:.88 (last specified file number inside parentheses)
58 ;" LogicB fields refer to file 5678 (last specified file number at same parentheses level)
59 ;" -- Each individual search term must be enclosed in parentheses, and may contain sub-terms
60 ;" enclosed in nested parentheses
61 ;" -- Each individual search term is comprised of:
62 ;" FIELD then COMPARATOR then VALUE
63 ;" 1. FIELDS -- can be name or number. This is for currently active file (see below)
64 ;" may also be FIELDA:FIELDB:... when FIELDA is a pointer, then FIELDB
65 ;" is taken from the pointed-to file. If FIELDB is not provided, and FIELDA
66 ;" is a pointer, then the .01 field of pointed-to-file. Individual field
67 ;" names may be inclosed in quotes
68 ;" 2. COMPARATOR -- can be:
69 ;" "=" -- means exact match
70 ;" "'=", "<>", -- any of these means Does-not-equal
71 ;" ">=", "'<" -- means greater-than-or-equal-to (same as not-less-than)
72 ;" "<=", "'>" -- means less-than-or-equal-to (same sa not-greater-than)
73 ;" "in","IN","In","{" -- means field is in specified rage (see Value below)
74 ;" When using IN, if field name is provided by NAME (not number),
75 ;" then field name should be inclosed in quotes to separate the
76 ;" letters of the field name from the letters of 'IN'.
77 ;" "[" -- means 'contains'. Interpreted as follows:
78 ;" -- For Word processor (WP) fields, this means that any line in the entire field
79 ;" can contain search term, to be matched positive.
80 ;" -- For free text field, then just text of field is searched.
81 ;" 3. VALUE -- The search term to search for. Should be in quotes.
82 ;" Note: if comparator is "IN", then syntax is "Value1..Value2"
83 ;" There should be a ".." between the two values.
84 ;" -- Logical combiners of separate search terms allowed are:
85 ;" "OR" or "|" or "||" or "!"
86 ;" "AND" or "&" or "&&"
87 ;" "NOT" or "'" or "ANDNOT"
