Search |
7.1 Different
levels and approaches:
1. easy / expert
2. menu/command driven
3. browsing term lists / indexes
4. query expressions
5. browsings record list |
| Pr: 1 yes (3) browsing
indexes + quick "Find" + assisted command
driven (2); 2 command driven, assisted by buttons but
syntax errors are possible; 3; 4; 5 |
En: 1 one QBE-query
by example template, also controls syntax; 4; 5 |
| Short Record list
browsing is default window, database dependent: one
record per line, can choose any field up to six; quick
find: enter string based upon sort key; sort on any
displayed field by clicking the column field bar |
Short record list
browsing is default window: one record per line can add
only RN to fixed: author, date, title. Cannot use term
lists here |
| RM: 1 Usually only expert; easy "Quick
reterieval" hidden in Term Manager; 2: command
driven, assisted by buttons;3: no, lists are to pick up
termsfor a query, not to index and display records at
once; 4; 5 |
|
| Short Record list browsing is
default window, not database dependent -and can apply to
all lists: one record per line, can choose any field (up
to 33); sort on any displayed field by clicking the
column field bar. Quick retrieval lets select terms but
only from Term Manager and launch <F12> a search
(AND or OR) |
|
7.2 Browsing the
Search Index
1. entries show number of related docs
2. relationships (e.g. x-refs) between entries are
displayed
3. direct selection of index terms and display of related
documents |
| Pr: 1; 2 n.a; 3 |
En: n.a. |
| RM: n.a. |
|
| 7.3 Query
expressions |
| Pr: assisted by command
buttons to select: fields, operators, terms, previous
queries |
En: assisted by template
and buttons to select fields, operators, (options: word,
indexes); lists' terms are available only by open and
copy/paste |
| RM: assisted by command buttons to
select: fields, operators, terms, previous queries |
|
| 7.4 Natural
language queries |
| Pr: no |
En: no |

cumulate previous queries still fully editable |

default); 3 no, only search on result |

7.15 Indexing
techniques
1. any character string
2. word by word
3. phrase (adjacent words)
4. marked portions of fields |

| RM: 1 in non-indexed fields; 2 in
non-indexed fields; 3 also more words inside the string
(indexed fields require truncation symbol) |
|

2. cluster of fields
3. full text = any field
4. same occurrence |

not using indexes; 4 |
| "contains"
is like "equal" = with implicit l/r truncation;
whereas explicit l/r truncation is used with *xxx*,
"=", or is taken as a string itself (no: AUTHOR
contains *ale*, but: AUTHOR contains ale or: AUTHOR =
*ale*) |

|
| Pr: no, only external
