A computer-readable recording medium stores therein a sequence-map generating program that causes a computer to execute extracting from files that include character strings written therein, a word having q (q>=2) characters; extracting from the word extracted at the extracting the word, consecutive characters from a character position s-th (1<=s<=q-r+1) from a head of the word to a character position determined by a number of characters r (r<=q); and generating, for each character position s-th from the head, a consecutive-character sequence map including a flag row that indicates, for each file, whether a file includes the consecutive characters extracted at the extracting the consecutive characters.
