1. 關鍵字查詢:可輸入局部或完整字串條件。
2. 查詢範例:
  「資料結構」:以一關鍵字為條件查詢。
  「宗教&問題」:兩條件必須同時符合。&(and符號)表示以交集處理。
  「資料|處理」:兩條件至少符合一項。|(直虛線)表示以聯集處理。
  「宗教&!問題」:符合「宗教」且沒有「問題」關鍵字之條件。!(驚嘆號)
3. 請避免使用太複雜的條件判斷,太多的&!|的條件處理運算子,系統效能將因此大大降低, 並影響線上其他查詢連線的正常使用。
4. 請避免使用太普及的用語或者過短的文字串。例如:在時間關鍵字中用'一'查詢;在科目名 稱中以'與'查詢;在教師姓名中以姓查詢。
1. Key word searching: you can key in the complete or a part of words.
2. example:
  “data structure”: use one key word as the condition for searching.
  “religion & problem”: Data should be cohered with both conditions. “&”[symbol for “and”] means that data would be handled with the intersection of conditions.
  “data | process”: Data should be cohered with at least one of the conditions. “|”[straight dotted line] means that data would be handled with the union of conditions.
  “religion &!problem”: Data should be cohered with the key word “religion” but not the one “problem”. “!” is the exclamation mark.
3. Please do not make the key words too complicated. Key words with too many “&!|” would decrease the efficiency of the system and affect the access of other on-line searching.
4. Please do not use the phrase that is too common or too short as the key word. For example, using “Monday” for searching date, using “and” for searching course, and using “last name” for searching teacher.
